A nice little game, though I don't understand how the limitation is being used, as the player can absolutely move, even being able to roll up the platform. I don't understand why this couldn't have been exported to play in the browser, but I have basically no experience with Unity so I don't know.
The idea is fine, but the execution is a little lacking in excitement. I liked the idea of the platform tilting so you can't linger on one side, but again the execution doesn't fit within the limitation as the player is able to move by itself up the platform. Had it been the platform that was tilted by the controls, it would've fit right in, but the way it's played is different enough from that that i feel it takes away from it in the context of this jam.
Barring that, it's fun for a little while, and most importantly it's a finished project, which is the greatest accomplishment you could ask for.
