Ok, I have several things to say:
1. I did not expect there would be sound effects for the player to fart.
2. It's really a well-made character. I really like how he can fart at any time, even when jumping. It's like giving a weapon, but instead of attacking the front, you attack the back. Great job!
3. I was hoping the fart to shrink as it goes up since it's gas. And I thought that the character would give some momentum when they fart.
Overall, it was a fun and interesting character. Good job!
