Well done! I enjoyed it.
My favourite detail was being able to push the tutorial text. I was actually expecting it to be needed in order to progress :)
By the way, I have a relatively powerful computer and I had performance issues, especially near the top of the levels. Also, the physics of the main character are a bit weird: when you land on a platform, if you are still going up then the game will launch you upwards, which can be used to skip some sections of the levels.
Good game overall! Well done!
