really cool concept and implementation of the theme!
gameplay is fun the and jump pads are very satisfying, there are some bugs I encountered where I got stuck between rocks and couldn't move, and where I just climbed a rock and got teleported back to the starting place, that was pretty annoying.
I also feel you could have made the atmosphere more menacing and dark and that would go well with the audio track, also I don't know if that intentional but the character is a bit blurred when jumping.
when you press continue I think i get someone else's progress, since I played for the first time.
overall I really liked it and I feel like there is a lot of potential here for a cool game, consider adding a time element like something chasing you (creature or a toxic gas or something)
