Thank for testing the game!
As one of the the programmer of the team, I totally understand what you mean, even I had some issues with how the game was played (as much on the gameplay side than the controls). Personnaly, it was my first game jam and it was sure a learning experience. I never really tried to implement most of the stuff I did in previous projects but now, I know what did go wrong. I don't know if you reached the end of the game, but you are basically softlocked when you are sent back to the menu because of the state of the mouse. Hoppefully the next one will be better!
