I really enjoyed this one.
At first the controls feel very very floaty, but being a dust sprite it kinda makes sense. Each mechanic is thought in a very clever way: a simple, yet effective “puzzle” to return back to the main world. The mechanics also work pretty well together.
Often I was like, no, I cannot make that jump, but then I tried, and it was possible :D My only feedback for this game would be to re-iterate on the movement feel a bit. This is probably something tricky to get right without losing the dust-personality controls
Played all the way to the end (what a cute ending) Very nicely done :)
