Thank you so much for the feedback!
I gotta study the sound situation in godot better, I thought I had it set so that the sfx would be quieter than the music but apparently that didn't work... getting rid of the losing screen is a great idea, it would help a ton with the flow of the game and the "R" bubble is something I already have available so it's an easy fix. About the big levels with the unknown sections, I wanted to add a "pan" feature with the mouse but ran out of time, so that's definitely a future feature, especially if i want to expand on the levels and add more stuff. I also wanted to make a level editor system, so that people could upload their levels online and challenge other players, but that's obviously way in the future ahahah
