Awesome artwork! The background looks fantastic in particular. And I like the idea of conserving your jump pads and using them sparingly, that's a cool twisting on platforming that I don't think I've seen. Also like how there's some secret crystals that encourage exploration of the level.
I did find myself a bit frustrated with a couple things: I don't think I had the ability to pickup a pad after having placed it? Also, I struggle the place the crystal after carrying it? I think some tutorial levels that more slowly introduce the mechanics would be super helpful!
