i didnt hate it man well done!
Cool game, well designed, the AI doesn't trip up too much.
Getting used to shooting takes a little time, and as with many games a little map knowledge works wonders.
In terms of controls, for a two player game, the WASD player has a notable disadvantage because without a little bit of fancy fingering moving around while shooting is just that little it harder. I would suggest a remap to include the shift or control keys, as these can be easily reached without changing hand position, or using two hands.
The "How to Play" section is cute, and well done, but it does almost make me wish for more target based games. Just throwing that out as an option.
Overall, it's a damn solid 2 player game, which is a rarity, so well done. 3.25 stars from me.
