Hey Mors, I recognize that you are a very talented game developer, I love your games, but in this one you have disappointed me by 3 factors that it has:
1. The characters move automatically, they make me too complicated from Level 3.
2. The Soundtracks they only last 6 or 7 seconds, and there is no looping between them.
3. In pause menu, It doesn't have the option of returning to the start menu in case anyone wants to leave the game without wasting 20 lives.
You should change those 3 problems to be better polished.
