It felt great after a long day at work. :D
Different versions of this should be developed and released; it's great for relieving stress. I loved the intro. The house collapsing on my head and the fly reappearing as if nothing happened was also funny.
The graphics, music, and gameplay are really enjoyable; congratulations and thank you.
The only thing that bothered me was the inability to mute the music and the mouse sensitivity. But these are minor details. It's a work above GameJam's level.
Greetings to the invincible fly.
