I think this is a cool idea, it's just dressed wrong (in my opinion).
This comes across to me as a puzzle game, but the game is using platforming design and a decimal precise game design. Which I feel works better for combat games or precision platformers.
I think the design of this game would have worked much better being gridbased. Each move is one energy, one grid movement. Rather than having it be a stamina type game. The reason I find this to be an issue is because, if I mess up with 10% stamina and I solved the puzzle, I feel like the game cheated me.
This could be solved by freezing the stamina when clearing the puzzle. But I still feel that gives too much room for errors. I can imagine a lot of players feeling frustrated by this design choice.
That said, I feel the game is pretty solid and you put a lot of effort and care into it. I understand the direction, but I feel a sort of disconnect with the intent and the way I experience the game.
Please keep making cool stuff. Rootin' for ya.
