Whoa! This is very polished game for a game jam entry! Awesome idea for a game. I imagined myself destroying those evil covid cells for good while playing this. xD I wish it would be that easy in real life... Other thing I wish is that there was more levels and some cool powerups, monster types etc.. There is no much replayability on it's current state. Oh and some other way to exit the game than Alt + F4 would be great ;)
All in all. Very good game and loved to see small polished things like animations, sound and gfx effects. Well done!
