The main lesson I learned is that for the next jams I should dedicate time for the play-testing. For me it was easy, so I was actually afraid that the game will be too easy. If we had play-tested the game and realized that the game is too hard I would implement optional checkpoints. Feel kinda bad that I actually did a shitty job at game design and didn't fully realize the potential of the game with such great visuals. But at least I learned the lesson and will do better next time
