Okay, now THAT is my kind of game !
Usually, in game jams, you don't see many shooters. That's probably because the genre was done and re-done. However, that kind of mindless fast-paced shooter is just my kind of game. I spend way, WAY more time on it than I anticipated, and I was glued to the screen all the while. You maxed out on Fun rating for me. Excellent !
Now, that's really nice and all, but there's also a few cons :
First, feedback ! I was so disappointed to not see any feedback when using the weapons or hitting the bad guys other than the quick fire animation. Feedback is an extremely important part of a game, and the player should feel rewarded for playing the game as the designer intended to. That's where feedback is critical. Your game is all about shooting an absurd amount of bad guys ? Loud crashing sounds on the shotguns, blood (Or whatever theses guys are made of) splattering everywhere and combos should be your priority.
There's also dodging. Sound for double jump, perhaps an animation on the weapon, and more air control on the double jump would be really awesome. Reward the player when using the jump, perhaps more damages/combos when shooting bad guys while in the air. Make it know that you intended it to be played that way.
Then, comes the theme's implementation. While it does make sense for an infinite game like this, just sacrificing some stats and numbers isn't very engaging. I think the theme's take could have been a little bit more creative beside just downing some stats (Perhaps actually sacrifice some gameplay elements, then, if the player does stay alive longer than that, then add stats sacrifice).
Finally, the last con I wanted to talk about, is the AI. It is easy to trick the bad guys into following you, and kill them off easily. it would be much more engaging and intense for the player if the AIs were actually thinking as a group instead of a single entity, trying to corner the player, and perhaps use projectiles. An AI Director in that case would have been a tremendous asset.
Now, I wrote such a wall of text for that game, that's just showing how much I enjoyed it, and everything I've said concerning the cons up there is only to help you make an ever better game next time. I already had a bundle of fun with this one, but it could be even better ;)
Also, I got up to wave 29. Died on wave 30, just too many bad guys x). I took a screenshot at wave 28 of them spawning :

I kept sacrificing my accuracy. At one point, it was below 1% for each gun x).
Finally, congratulations for your first Ludum Dare entry ! It was a very nice one !
