Well thankfully, Eternity Studio isn't too great a maze. There are much worse raw mazes, and some annoying puzzles you're going to come up against. But take it from me, mapping the area gets easier every time. I can now blow through the studio in about twenty-five minutes, Ogma's house in less than fifteen.

Honestly, dragon is an extremely underwhelming type in the manamon universe. It's resisted by stone and holy, and magic is immune to it. The only thing that dragon is super-effective against is...uh, other dragon types. There are four fully-evolved dragon types, and two of those aren't dragons till level 32 and level 55. As such, I tend to use Volanteral as a heavy hitter with Assault Gem, because only a couple of types wall stone (like earth and fighting, both of which can be hit hard by dragon attacks, unless they're named Grandlan, at which point you're kind of screwed). Grandlan is a hard counter to Volanteral. Also, Shields Up on this thing is an insane ability, since it means that you're almost guaranteed to live through the first hit and slam back huge damage on whatever shows up. In group battles, you can team up on Volanteral and kill it before it gets to hit, but even then, you're diverting multiple attacks to shut it down which leaves the rest of the team to wail on everything else.

How about Volanteral with its ability and then equipped with ambush guardian? Can you stack it like that or are you better off using chrono core because it's going to take a hit and should probably be able to heal back some every time it kills something? On an unrelated note, just for fun I tanked the Oghma fight to see what Andromeda would do if her whole team was dead. Looks like your team is the only one that gets healed.

Ambush Guard is decent for anything with Shields Up, but Chrono Core is arguably better, since unless ie takes insane damage, he'll actually be able to heal maybe back up to full health if he KOs stuff. Alternatively, secondary scale uniform works well on this guy as well as Dragomier.

For me, ethernity studio is as difficult as the shadow kingdom.
But there's also a trap test later on. For me, it's tougher that the ethernity studio.

I don't think so.
For me, the trap test is much more difficult and flustrating than shadow kingdom f5.

At times, it really starts to seem like Aaron has run out of gas and resorted to simply tossing in mix-and-match versions of things you'd already seen. The hyper Grandlan is a new hyper, but no, it really isn't. It's merely a combination of the other bosses. It spins red and white webs. Where have you seen that before? It counters your moves with a type that's effective against the type of the move you just used. Where have you seen that before? How about the spike rooms. Does anyone else get the feeling that they just drag on endlessly? This game is big, but without all the repetition, it would be much, much shorter. By the time you get to Ascendance Path, it would have been nice to see some new things rather than just more variations of the same crap. That and all the random luck that determines the outcome of fights are the most frustrating parts of this game for me.

Oh I don't regret buying either game. Not even a little bit. Paladin of the Sky is a bit of a different story though. I played it once, and more than likely won't ever play it again. But as I've said on here before, Aaron Baker has provided me with countless hours of entertainment through the two Manamon games alone.

Zuckuss, I really hate to say this straight-out like this, but I'm going to anyway. Please read this thoroughly.
You are really not in a great position to be criticizing game balance. Yes, I said it.
The reason I said this comes down to the following:
1. You'd cheat if you could
2. You refused to buy the game until people made walkthroughs
3. You will take virtually any chance to make a game easier
This alone is enough for me to seriously call your opinions about game balance into question. I'll answer your issues each by each though.
Moving spikes...if you're talking about Barren Underground, I wish each room had been different. One full of spikes, one full of conveyor belts and electric floors, and one full of electric bolts (the moving ones) and lasers, or some other traps. I do wish each room were different, but I'm glad there are multiple rooms and doors and keys. To me, this makes that area one of my favourite in the game, honestly.
And yes, the stupid hyper thing should be restoring health while it puts out bomb boxes and uses a shield and whatnot. I'm not a huge, huge fan of this boss, but I like it way, way more than Irroadium from the first game. It requires strategy and some planning. It requires you to actually think about how you want to prioritize things. Usually, moves with a power greater than 80 or 85 are best on the boss, because you will lower the turn number it takes to bring it down. So yes, the healing once it gets below x health will increase the difficulty, but not to an unreasonable degree.
As for mazes? I feel like manamon 1 is worse for this, with the huge exceptions of the swamp and catacombs. Every other area was relatively okay when it comes to mazes. By contrast, manamon 1 had a lot of dead ends and pointless digressions in Ascendance Path, Tangeria Tower and Starwalk Mountain. Let's also not forget Irroadium's room - or was it Ziognioss - where you have literally thousands of tiles of open space for no other reason than that you can hear the slap-slap of your footsteps as you head toward the mythical you want to catch? This is in keeping with pokemon and other similar games, where mazelike elements are part of game navigation. Manamon does it a bit more, and sometimes to its detriment, but I don't think this is a fatal weakness. If you want all maps to be linear, one-way, and to point you from one objective to the next without any way to get lost, turned around, confused or able to venture down side paths, I'd warrant that this is a reflection of your personal values.
So why am I calling this out? Because while I do feel Manamon 2 has many flaws, the things you pointed out...really don't qualify much IMO. These elements are part of what makes the game good, and part of what contributes to its longevity. If everything is safe, predictable and boring, what the hell sort of game is that? Rather than ascribing to Aaron the arrogance implicit in "aren't I amazing", how about we give him credit for doing more than just moving guards, fireballs, lasers and electricity? I think this was one area where manamon 2 is head and shoulders above its predecessor.

Also, to whoever said the game is only worth fifteen bucks...nah. I'd say twenty-five, maybe thirty. Forty seems a bit spendy, given that the jump in other aspects of development was not as significant as three years of downtime would've led me to expect. I've cited those shortcomings many times elsewhere.

A hyper boss that puts up bombs, and restores health, I haven't seen that yet, but I'm guessing that's the Hyper Hathorilian that I've read about. Now this might be a bit off topic, but I'm posting it hear anyway since I haven't seen it using the search feature. Will I miss any good attacks if I transform Cowmoono before level 30? I just don't want to miss out on something strong, like Staff Slash or Righchus Rend, assuming one of those is physical. He's only level 29 right now, the rest of my team is 32. Montor just got Superspark. In my oppinion, at least, he's one of my favorite electric Manamon, Jimitron coming second. Regarding not liking the game, I haven't beaten it, but I think both of them are good. I like Manamon 2 more than 1, but 1 isn't bad. I still have a lot more to try with Manamon 2, including those Paladin of the Sky bosses if they're really part of the game. Remember, the farthest I've gotten is Barren Byron. Iternity Studio, I think Shadow Kingdom is harder because of the guards and the timed rooms. Irodium, though, pound on him with Power Kick and Meteor Rush. Once you know how to fight him, he's like, just another tamer battle.

So, just out of curiosity, and anyone can answer.

Which Manamon in Manamon 2 are, in your opinion at least, not realizing their full potential? For me, Jagzeom is the one that disappointed me. It starts out with good stats and a pretty good move set, but doesn't, as far as I can tell pick up any moves over 90 power after level 47 or so. If this Manamon got more powerful undead moves to match its great stats, it could give Fiendour a run for its money.

There is a boss that alternates between putting up a shield you have to break through, and a bomb box you have to kill before it blows up. Not every round, of course, but that's one of the gimmicks. Having beaten the game a few times, I know what to expect, so I'm ready for it. My team is around level 60 for that boss, so I just bull through it. By the time he drops the bomb box, he's pretty much dead. So I finish killing him then kill the bomb box. I lose some mons through that whole sequence, but it doesn't matter that much. I'm still in no danger of losing.

Zinbat's line appears to be making an attempt at being a support mon, with stuff like team immunity. Except, what's the point of putting that on one of the squishiest mons out there? Setting up will just kill you.

Oh well, at least its a non-holy type that tries to be support. There aren't too many of those out there. A fair few mons get one or two support moves, but almost all true support mons are holy. Domestress is one exception I can think of, are there any others?
