Wow. Amazed yet again.
For once someone did something GOOD with stick figures.
I thought the "power-up" weapons were kinda lame and useless mostly, since they didn't stun the enemies at all to keep them from hitting you back. Mostly I just jump-kicked through the whole thing. The end of the game was kinda nifty though, cause I got out with exactly 1 second left on the clock.
The survival mode was pretty nifty, though I thought the weapons dropped rather infrequently. I know a lot of times I was really needing that big rifle, but never got it... IT REALLY NEEDS a button to pick up/use a weapon... I don't know how many times I accidentally picked one up. Instead of holding down space NOT to... you should be able to press space TO pick them up.
Anyway, great game! Keep it up!
Oh, and the transitions between scenes were really great! They reminded me of a DVD menu.
