The fart sounds when you hit the walls were a nice touch.
A timer would be a neat addition so there could be some sort of scoring.
The visuals were alright for the most part, I liked the intestines path although the background was a bit too samey, maaaaybe you guys could have gone ballistic in there? Just a thought.
The audio was nice for the sound effects but the song could have been somewhat more into comedic and ludicrous? Seemed a bit repetitive.
One thing I found weird was that shooting the smaller poops took longer to kill them while the big ones died almost instantly. Felt like maybe I should have shot one more at them, but not much of a big deal.
Once I finished it for the first time I thought the game crashed because it just closed suddenly.
Congratulations on your first game!
