Nice work. I was able to find all the orbs and man can the player character move. It borders on a bit to fast for precision jumps for me but that's just an opinion. The cave was a bit too dark for me and felt straining on the eyes keeping track of the player, especially because it required the most precise jumping.
Overall I really enjoyed it, while I wouldn't say it's easy to complete anyone can pick it up and jump around with ease. Well done.
