I am currently working on an audio walkthrough of the rainbow tower game. It is a very difficult one to be sure. I'm currently editing and hope to upload it today. If you like I can do one for the cannonball game too.

Basically the goal of the cannonball game is to throw a cannonball from the start of the track to the end. At the end of the track there's a chasm though, and if the cannonball falls into it, you'll lose that round.

When the game begins, you start at the chasm, and are led back to the start of the track. Listen to this carefully, as it is the only way to know how far to throw the cannonball. When the gunshot is heard, hold F for a few seconds and release it. The longer you hold F, the farther the cannonball will go, but don't let it fall into the chasm! It takes experimentation to get it down, and I'm still not very good at it, but in time I think I'll get it down as I think there's a method to get it nearly perfect. For each cannonball, you will be told how far it stopped from the chasm, so if it stops more than 5 steps away, you should probably hold F for a second or so longer than you did last time. You can use the powering-up churpy noises to gauge the distance, this would be easier to show on a recording.

The game doesn't start off at -20 points, because the maximum you can get per cannonball is 5 points, and you only get 4 attempts. Meaning that if you do everything spotlessly perfect, you'd still only get 20 points and would draw with 0 at the end of the game. If the cannonball falls into the chasm, you'll lose 5 points though, which I suspect is what's happening for you.

Dice game is pretty cool once you get it sorted out. Having previous knowledge of how a dye works helps. However the bike game I hate so much. I can not get through it no matter how many times I try. Hate hate hate!

The bike game is really very simple: you have four lanes and bikes travel down these lanes. If you are in the same lane as an oncoming bike and don't move out of the way, you'll get squashed. What makes it so frustrating is that the lanes are only one step apart and the panning differences are extremely slight. That, and the bike sounds are a little quiet and hard to distinguish. If he would separate the panning on that game so that there was actually a wide separation, it would actually be doable. As it is, I normally have to use control F5 and F6 to adjust the pan/volume scaling (an undocumented feature, but one that does exist). For me, I have to set that to 6 or so, and set my bike to the slowest speed. I can get 20 points this way if I stay alert, but it is not something I particularly enjoy. For the rest of the games I set the pan scaling back to 2 or 3 (2 is default).

Well, the control f5 and f6 do not work for the panning volume.

At f5 and f6 do not work either. I also know there is a way to adjust the degree of pitch on the sounds, but I have no idea what the keystrokes are.

Yep, that biking one is a pain.
Give me cannon ball rolling any time, even if its hard, its much more fun then getting run over.

yeah, that dice game is just, rjskldvouopirasdfj, how do people manage to do that.

agreed. I'm horrible at minigames anyway; the least they could do is start me at 0.

thanks for the panning and sound tip adjustments, i had no clue they existed:) after making necessary adjustments i saved current sound settings:)

regarding numbered slabs:
I have detailed the procedure here (posts 25 and 26) and clarified information specific to the game (post 1550)

so practicing for a bit should get you a decent score so you can at least pass the game. But, as always, practice practice practice really helps, thankfully liam's Slide game is a really good starter.

I really like the concept of Rainbow Tower, but it's extremely difficult. It could be tweaked a bit to make it more manageable, but I wouldn't want it to be removed.

aww come on, rainbow tower is totally doable, probably yes a bit harder than most games that do not have hardcore mode, but hidden palace beats it. The dice game is also easy provided you do understand how the numbers change when you move the arrows.
Oh yeah, what about the dragon scales game... lol lets talk about THAT!
its really funny how some people get a hacked file and then fail miserably at some really obvious games like cannonball throwing or stopwatch corridor. Worst part, they do host servers, so really not sure what they are trying to accomplish there.
