Awesome game with simple mechanics and really clever level design. Some of the cycles were really tricky and I sometimes had to pause a moment to really plan my strategy out. There were also some really tough jumps that I loved. This one in particular was diabolical, and it felt so satisfying when I finally nailed the execution.
I cleared in about 45 minutes but I only managed to find two of the secret walls, so I've definitely missed a lot. I'll have to play it again some time and hunt down the rest. Thanks for the game!
