I enjoyed the game, thank you for sharing it.
I found the levels at the start were a bit too small, I could usually skip straight over the top of them all once I figured out what i needed to do. I also found that the character was hard to control whilst you were moving so fast.
I enjoyed the concept though, and as much as it felt like cheating, hoping over the top of the first walls was quite satisfying. I managed to get to level 28 before getting lost.
