HI, the idea is cool and fun but there are 2 things that I think are really problematic and hold it back:
The death animation is really slow. Painfully slow. And since it puts you back into "visible mode" every time you die, it takes so much time just to retry the level in blind mode. In the more tricky levels, it adds ton of busy work and frustration.
And the other thing is the controls. You don't explain that there is a double jump, and I actually don't understand, why have 2 super short jumps when you can have 1 normal jump?
