The game idea is pretty interesting, it would be cool if you could do more things with the chain! Like putting your chain against 2 poles and then using it like a slingshot!
Slight nitpick: The music doesn’t quite fit the feel of the game. I’d imagine something like ambiance would fit better.
I feel like the game should immediately teleport the player to the highest checkpoint they have unlocked instead of them having to go through the checkpoint menu. Also, when I teleported to the checkpoint, my chain got stuck under the checkpoint platform, which was a mild inconvenience.
