Starts getting harder after ten levels. It took me a while to realize that thing that you only need to press left or right to wall jump (took till I read the description in search for clues), but it actually makes the gameplay simpler, even if it's a bit a confusing configuration at first. I like the simple level design, even if I was expecting more simplicity even with the latter levels. For the yellow door, it looks like the character's moving in behind it rather than through it. The ambient soundscape in the background's real nice. Keep it going!
