I am playing on a 3Gs. Seems pretty good to me. Some of the movements seem to lag, then go really fast, making the game play a little awkward. But still able to play. Pretty fun title. Graphics look good. Plays much faster on mine then was deomnstrated on the video though, probably due to hardware speed differences...
Ok, put in a couple games on my lunch break, as far as I can tell no problems came up. The game does stutter ever so slightly here and there, but it's sort of always done that. Made it to the third level in each game, and then died repeatedly. It's actually not as hard as I remember, and I can't believe I don't play this one more. It's super fun! I'm gonna see if I can get to the last level, even if it's on the easy setting. People should snatch this one up while it's a dollar, great game!
Okay, now here is my weird but CRUCIAL default question. Does the game mix stuff up every play through? Like start off on the first level, do absolutely nothing (if possible), do the baddies always come at you from the same points dropping the same powerups?
Ahhhhh, I forgot about your need for random generation No, the enemies and powerups don't seem to be random. But this game is so frantic, it might still work for you. I'll have to do a little detective work and see if the enemies are different based on the level of difficulty. This game reminds me of Space Harrier, so if anybody ever liked that game then you'd probably really enjoy this one, for what that's worth.
