Overall I really liked the experience. At the start I just drew bridges with the pen, and every time I got hit I restarted.
Eventually I noticed I can keep drawing if I get hit, and after the platforms disappeared I started jumping and drawing under me to basically go where I want without needing platforms or bridges.
So that part was really cool, having the player get better just by playing the game. But I just assumed if I changed the world and then go in the door I would progress or win something.
Overall it was very excellent I loved the character design and the mechanics. And it felt really original and authentic. So thank you very much
