Hi, thanks a lot !
A bunch of people told me about the grain end bugs (I had solved but uploaded the wrong version T_T) and other things that could be improved. I will work on it tomorrow and release an improved version when the jam is over, so if you have more advice you want to share or want to come back try the new version after the jam ends I'll be happy to get your feedback again !
Also, I'm a learning solo dev so feedback helps a lot and motivates me. So your compliment makes me very happy and motivated to do more :D
