Really clever idea! I saw the first screen and thought: "hah, a platformer with hex tiles, am I gonna bump up and down constantly on flat ground?" and was immediately pleased to see that was the case, and that it was a core mechanic of the game!
I didn't manage to beat the game, the puzzles were too tricky for me, and the control layout wasn't ergonomic. I kept forgetting which key was which and having to move my hand all the time distracted from trying to solve the puzzles.
