Cool idea but it is quite hard. As a good rule of thumb, make your game way easier than you think it should be. People who have never played your game before are going to struggle a lot more than the person who invented the game.
When level are handcraft it is easy to do that. Now they are procedurally with a lot of parameter to control, with this game jam and all, same old story I didn't have time left to balance the game in the end. Thank for the feedback mate.
