Took me a while to figure out there was a walljump, could do with a tutorial.
Interesting application of the 2 button limitation. Decent challenge, and optional collectables are done very well here (not necessary but add to the skill requirement). Jumping feels a bit janky but this is a gamejam :).
My main issue is that because you can only turn when you hit a wall, depending on level design it can take you a long time to retry a jump that you missed and got turned around on.
Theme is appropriate but does not factor into gameplay in any way.
