I love the idea of the game, super original! If you go farther with this game I'd really like to see randomly generated terrain and something to make me more ready for what's coming up next. I found it quite difficult because most of the time I didn't know what was coming up next till my third time to that part so I would often jump when I see a hole but then a wall will come into view and I smash into it. If you were able to flip sides whilst still in the air that would keep the game difficult whilst still fixing this issue.
The adherence to the theme is kinda loose, with only one direction. I didn't know how it tied into the theme until I read the description of it. I think if you tied in that narrative of "only one reason" that you planned it would have really solidified the theme into the game.
