It is very difficult. but the idea is really interesting. By the way, if you go to the menu from one level and select another level, the music will start several times. I think it would be nice to let the player get used to the game smoothly, for example, at the second level, for a very long time I could not figure out how to get through it.

Thank you for the feedback ! We knew that the game was very difficult but we didn't have enough time to create new easier levels because we were able to test the levels that one of us had created only two hours before the game jam ended and we still had to fix tons of bugs. That's also why we forgot to stop the level music when you go back to the menu.
