Funny ending and maybe theres something fun with the concept if it was fleshed out more. I think the platforming and level design needs quite a bit for a few reasons:

There is flyback on wall jumps which is annoying and unusual for walljumps in other games, also affects wall grabs I feel, makes the whole traversal worse.

The lit area is way too small, You are making blind jumps and blind falls that may reset you or might be the correct route. Level design is not super intuitive as well partly because of the previous reason.

Some background elements are pretty similar looking to platforming elements which is momentarily confusing.

congrats on the release!

I was not expecting that! I like the presentation and the gameplay is smooth. (i would also like to jump with space though)  Really cool! :)

Now way it's chess! I know this game !
The jumps were a little too blind for me, didn't make the game very enjoyable :( 

Wall jump feels good but only with two jump buttons !
