I'm a big fan of this game - it's a huge shame it doesn't have more ratings as I wish more people had the chance to play it! I loved all the sound effects - very effective use there, although I would have liked a sound and maybe a screen shake for falling in the lava. The music fitted very well, I liked that a lot. To improve, maybe consider mouse controls rather than arrow controls, as these caught me off guard a few times in my rotating adventures. That in mind, this could absolutely be ported to mobile with a few tweaks, something to consider!
Well done!
