A very creative approach to platforming with just 2 buttons. There were some issues tho, especially with the double jump that is confusing and not very consistent.

The wall jump is kinda reliable, but it could be improved by a bit if it was "side" agnostic. For instance, you wouldn't need to keep pressing left if you are sliding in a wall on left. As long as you press the 2 buttons and you were in a wall in the last, let's say 0.5 seconds, it would perform the wall jump.

The BGM melody is nice, but that pitchy instrument is really off, tho. I'd pick something with more harmonics and depth.
