Beat the game 3 times, I like it.
There's work to do to make this puzzle work without reading the comments. For example, a little tutorial level where you can open the chest with energy walk and a portal to another level. Random abilities will work if there's a restart button, bit it feels like you got one if you played it one time.
Also a level is too big and empty for this slow movement, so it needs balance.
But overall it's great! I'd replay it with more levels and variety. Keep it up!
