Overall fantastic. Not too hard, and just the right length. One minor point--the hintbox for trampolines comes several levels after you first encounter them. Plus, cannons never have a hintbox (though it's easy enough to figure out), though that could have been because you didn't have time to include them in any real levels.
There's so much good about this game that I'm conflicted. The art and music is excellent. However, there are many minor things that detract from the overall experience. No semi-transparency on props means that I can end up fighting monsters I can't see. No arrows on exits means there's no easy way to tell where they are. It's ok to have both the keyboard and mouse control the character, but why bother why the keyboard if everything else is done through the mouse (no hotkeys, no way of attacking without clicking on a monster). I'd rather just see it be entirely through the mouse.
Kind of sucks having almost all of the achievements be "find X in X games in a row". You should just change it so it doesn't have to be in a row. That's just aggravating.
Unless I'm mistaken there's at least one un-credited song...in some of the levels, before you start infecting people Saskrotch's "Warming Up" is playing. He isn't listed in the credits though. For example, go to California: http://www.youtube.com/watch?v=hJw1ZSmDoSc
The AI in this game is awful. Without actual patrol routes this means that guards will just randomly flip around or run back and forth in the same hallway. Why can't you kill them either?
Why did this get badges? Since you're a 2d character on a 3d playing field, it's hard to tell where you actually are so I found myself clipping through ledges. The difficulty in levels seems to vary erratically, and I'll get stuck on one level only to breeze through the next four. It's annoying that you can change sides while airborne, since this meant I had trouble aiming my jumps since half the time I would accidentally rotate and fall into a hole. Why do you lose momentum when you change sides?
The timer in between waves is a bit annoying. Some of the recharge times seem a bit excessively long. Plus, somehow my collectors got glitched and now I have three collectors that are on top of each other (in other words, I basically lost two collectors).
It's ok, but there really should be a "keep weapon" feature. It's so annoying when I end up accidentally picking up some crappy weapon and it gets rid of my good one. Also, I found the fastest ship to be completely unplayable, but the average ship seems to control fine.
I'm so upset. This game could've been great but it's just frustrating. Shots never go where I aim them. I managed to get seeking missiles (I thought?) except they never home in correctly. Level ups seem to give out random numbers of mutations and spawns. The edges of rooms aren't hard (or whatever you want to call it) so you can get knocked into another room (especially during boss fights) and end up summoning even more enemies to deal with. There's no good way to test out builds to see how adding different cells will affect your ship.
Don't get me wrong, it's a pretty neat idea. But for now? I'll stick with Bubble Tanks.
