I got stuck on the "you need some luck" screen, bouncing off the walls when you're on the ground was annoying for the precise platforming areas. Fun otherwise. Good job for one person and 2 days
You're right, it's not a bad job... but as you said for two days, and the jam lasted 3... for the rest, I can say that you may not accelerate at full speed, and you can also fly very high if you press W immediately after jumping through Space.
