The gimmick certainly adds more depth to an already well-made platformer.

As a side note, my younger brother is really good at your game.

This was a great concept and it was fun!  I only found myself stuck a few times (but it was frustrating when I would get stuck of course).  I really want to know how you did the background visual effect!

Very interesting idea!

Beautiful visual style with music and sound to complement it. The mechanic of not being able to see where you were going the second time you walk the same place is very great but I feel it hasn't been utilized enough. Great game overall.

Nice idea here! Could very well be expanded into a deeper mechanic, with some more additions. Having to rely on knowing where you character is via sounds, and paying attention to where you go incase you'll need to see clearer there. Found myself having a bit of trouble getting consistent wall jumps, but that's probably just me with arrow controls. 

Visuals are clean and nice, audio is great! Overall a cool idea that could be expanded very well into a larger game! 

Very satisfying!

Extremely clever underlying mechanic which doubles-up as a really impressive visual style. I do like the idea here, and the levels are cleverly thought through. It's always a bit frustrating when a game's main difficulty comes from not being able to see what you're doing, but you know what you're getting into from the start with this one!

A good platformer with an interesting idea! =)
