Interesting concept, but the controls, and level design leave much to be desired. The controls are just too loose and a platformer depends on having tight controls so it relies on the skill of the player rather than finessing poor controls. The level design wasn't as bad, and suffers to some extent because of the poor controls, but particularly putting hazards near where a new screen is entered is cheap and frustrating rather than challenging. Also requiring some very finicky jumps with the poor controls makes some of the areas with a lot of them between save points annoying with all the redoes. The last falling section particularly suffers from both the poor controls and level design because the control physics are so loose, and not being able to see where I was falling, it was more just straight up luck than skill.
The positives are that the graphics and concept are solid. With a little more work, I could see this being a solid game.
