Thank you for you insight =) !
I agree with pretty much everything you said ^^. We had a lot of ideas, tried to fit a maximum of things inside the game, and ended up with a lot of unpolished features that we couldn't tune properly because, well, 50h is short x). The big lesson we learned during that jam is "quantity != quality", and it would have been better to scrap some features to polish the others.
The sound crackling is on our end, it only happens in the web build, but not in the windows build or the editor... We are still investigating why xD.
Thank you again for your valuable review, it shed light on a lot of things we can improve on for the next jam =D !
