I like the premise (apparently I'm supposed to be chased by coronavirus), it is a solid concept to start, although I do have a few recommendations. First, apparently the virus doesn't make an appearance early on in the game, I think it would be better if it was there the whole time (maybe doesn't move until player makes the first move). Also, I found a shrink powerup somewhere, which was cool, I guess that would help me fit through gaps but I think it would be nice if you explain the powerups more in the beginning. Also, don't be afraid to spice up the assets! Everything felt kind of muted. I didn't know my end goal either, maybe a minimap with a finish flag or a side character who gives you advice would be nice.
Don't take this list of feedback too critically, I think you are off to a really good start and have a strong foundation for your game! If you just make the game pop a little more with more assets and music, as well as give the player more direction, you'd have an amazing game!
