I dig the mechanics for this game!! It was fun to jump around and try to stay alive! However, I think the scoring system should be tied to how many flies you've killed instead of time alive. Maybe that could be a different mode? But, I had a lot of fun playing this one. Good job! 

This is one of the more well polished games from this jam! I'm kinda confused as to why a spider is running away from flies tho.

Nice twist on the theme.

I think the shooting could use some more polish. I played on normal dificulty, and for me it was mostly spamming LMB. Probably having an automatic mode would be nice, and maybe "ammo" pickups of some sort so the player would need to avoid the flies instead of shooting them if they run out of ammo.

Cool backgrounds by the way!
