thank you for the feedback! I didn't think the controls were hard to deal with, I'm sorry for the inconvenience. Originally I planned to add a key remapping function in the option menu but I didn't manage to do that in the end.
When this jam will end I plan to add some new features to the game if I manage to (this is actually my very first game published and my very first developed in Godot) and key remapping will certainly be one of them!
