What I particularly loved about this game was the "Covid Balls" coming at me out of nowhere. That added a nice surprise to the game and it definitely caught me off guard multiple times. I also liked the flashlight effect that you added where light is cast in the direction that the player is looking at. What I would suggest you add would be a lives counter or a way of being able to restart the game once the player dies.
Overall I enjoyed this game a lot because there was no easy route to finding the mask which forced me to look around and explore the map more. I also thought it was funny how you named your projectile shooter "Purell" and how you related it to the overall theme of the game.
