Nice puzzle game. The progression feels a bit hard and had to try some things blindly. Levels are really hard, that's great but maybe not for all. Interesting concept, kudos
In response to "had to try some things blindly": I had to do the same at the beginning. However, I personally thought it worked well for progression. Each time those blind actions were rewarded, I felt like I learned a bit more about the mechanics. It was awesome when it finally "clicked".
