Nice to see a game similar to my own.
Very simple and elegant and well crafted game.
The tutorial is impressive as it actually explains how the game works very well.
Easily one of the most solid entries to the jam I've played. Well done all around.
only criticisms:
1. instead of a button to change between kick/keep it would be nice to use left mouse button and right mouse button.
2. as far as I can see, there's no logical reason to choose one of the zombies in level 6 over the other, and so you have to rely on using your lives in order to make a guess.
3. a game won "congratulations, you won!" screen or something would have been nice.
