Really nice short game! Adding the secret rooms was pretty cool also. I think though in order for the player to know if he collected all orbs the UI may say like x / 25 orbs. There are few stuff from game that can be improve, and most of them were mentioned, but there was one that my eyes kept looking at and was that whenever you jumped the sprite will reset facing left. Overall, great job! is a really fun platformer game to play. Congrats on your entry
