I actually enjoyed your game, really liked the idea. I just have some feedback if you wanna update it after jam...
bullets can go through the buildings and it makes it a little easier to kill aliens.
there is a bug that humans can't move around some times.
there is no cooldown time for memory eraser and I can spam it.
and also infinite fire rate for the laser gun which I can spam so fast.
after the game end, you can still shoot the gun and if you use your memory eraser the screen goes white and the score can't be read.
