Really awesome with the XP visuals and music.
Quite a challenging platformer with multiple mechanics you need to master. It was interesting trying to puzzle out how to solve a given level. Level 4 was quite difficult to me, but eventually solving it felt great.
The controls are too slippery for my liking. Maybe you did it on purpose to make it harder, but to me it is no fun. The difficulty should come from other places.
And I still don't understand what the incognito ability does?
But overall, I am impressed with what you've set out to do, and you have executed it well.
