Awesome job man. You've received a lot of feedback so I'll attempt not to repeat a lot from other reviews:
The controls are simple but extremely satisfying. I was getting a dopamine rush with every jump I nailed.
It's already been said but your character design is awesome, Special mention to Trice and his little crafty hands as he summons flies to attack, and to the dove that intentionally or not looked like he was flexing every time he flapped.
It could just be me but while the music was good it didn't really fit the aesthetic of the game and after awhile It became a little grating.
It's awesome that you made this on your own! especially something that feels so complete. Keep up the good work!
