Respect, for a solo entry done in 10 hours at your age :o
I like the use of lighting for atmosphere, and the covid sprites are funny with their googly eyes.
Just some small issues i'd point out but nothing much really, the game doesn't make it obvious at first that you can move around to different room in the hospital, so at first i thought it was just an arena untill i saw the gap in the wall, the weapon is fine but i feel it would be better to have it auto shoot when maintaining the click instead of spamming it, and last sometimes in rooms where there are a lot of enemies their sound can get a bit loud, but that's about it and like i said these are some rather small issues plus gotta take into account the jam's deadline.
Anyway, good job and keep at it :)
