Interesting concept! I was pleasantly surprised by the graphics and the challenge! Yes, sometimes it gets difficult to memorize the current control config, displaying it as a UI in each level after you pressed every direction would help a lot! Not everyone has perfect memory, especially when you have 0.3 seconds until you fall off, and accidentally press the wrong button... A bit more audio fx would have been great! Other than that, you pulled off a solid game! Hope you make more creative ones like this ;)
