I don't know how this would work in the code, but I think it would be very cool if you had a significantly lower chance of making a hit when you attack on the same side you blocked from.
Right now you basically just have to press the key twice and that just doesn't feel like fencing, it isn't very challenging and it just ends up feeling like a game of chance.
Not saying you shouldn't be able to make a hit, just that it should be harder that way.
I also wish that the successful attack and enemy death sounds would actually happen on the side you swung from, instead of a random one, makes it seem more realistic that way.
Another suggestion is to make up arrow the center attack key, personally using the down arrow never really made sense to me, it feels more satisfying that way, the blind swordsmen and a blind legend already use it for a reason, and it's easier for your fingers when using a laptop too.
Maybe you could use the down arrow for taunts? That would be cool...
I'm wondering why you don't start out with allot more health on survival mode, I know it's supposed to be a challenge, but I can't imagine most people getting through even 3 Sith this way...
The more I play it the more I enjoy this game though, even if it's missing some stuff like cutting sounds for attacks, and deflecting blaster bolts, or force moves, but hey, that could happen later... And it still has high quality sounds and music, very satisfying to kill your enemy as well! :-)
Oh, one thing, I noticed that when your enemy gets to 29 percent health, it takes way more tries than usual to get a hit; I suppose this could be a fluke, but it's happened to me three times now.
Looking forward to 2.1, thanks for fixing the bugs so fast!
