This was pretty fun! I especially loved the SFX and music, along with the mini game to clean up the bug guts. I did run into some pretty significant bugs (not flies, unfortunately) early on, though. Most of my issues came in the 2nd level, and prevented me from continuing with the game. I'd get every fly, but my health would go down for some reason at seemingly random intervals. It might be possible that there are flies spawning off-screen, so I don't even see them before they go to the top of the screen. If it changes anything, I'm on a Pixel 4a on Chrome. Otherwise, I enjoyed what I saw!
