I thought the concept of the game was really cool. Having to use the reward from a different puzzle to solve a new one felt neat, but since that was the case I'm not sure why you didn't just make it a linear path instead of having the illusion of choice at the beginning. The assets and overall look of the game was pretty good too.
Also on the level where you use binoculars to make the false platforms fall off you can still walk over where they were and be ok. Minor thing but it was a funny little glitch
