True dat, guy below me.
Machine Guns and Shotguns are waaay too good. Tone 'em down a bit, I got full perfects using only those two. Also, add a way to restart the level or return to the menu in-game (I would say pause, but between waves is pretty much pause). Also, for the upgrade button, make it so that it recognizes the whole area around the word upgrade, instead of the little plus. It's really hard to hit the plus in the heat of a battle.
Fun game, great\ graphics, sound, and music. Fairly balanced and addictive gameplay. I give you 5/5!
Can't wait for the final version!

Pro: F*CKING AWESOME GAME!!!! Great gameplay, innovative card thingy system, great replay value, tons of WTF-How-Did-I-Do-That moments.
Con: NO SAVE!!!!! :(. I couldn't finish because i didn't have enough time in one sitting. Also, no way to upgrade your super attack (which is very anticlimactic btw. It's superawesome looking, but still did a lot weaker than your normal shot). Also, lasers are the same color as enemy shots, making it very confusing/scary. Bosses don't really fit with the rest of the art. Mostly visual, not gameplay.
Overall: Great Work 5/5
Fun game. Wish sandbox mode were more accessible. But you can still get 2 it by making a game, going in to advanced options, and making it private, so no one can join.
