Needing to remember where the light went and make inferences about the shape of the maze is very original. Smashing yourself into walls with every move fits the limitation very well. The sound and art are excellent as well.
I'm don't think everyone will feel this way, but while playing I wanted to halt the light early by pressing in a direction-- waiting for the light to flash every time made redoing the level less streamlined than it could be. I could see the argument for making sure the player gets time to fully absorb the information they're seeing about the maze shape, though. Everything else about the game felt perfectly tuned, this game is an extremely strong entry.
