Totally unfair game. The collision are a bit clunky. But what I like the most it the strangeness of certain mechanic. Sometimes you just have to walk on the void. For the lava, you can walk through the wall, wait for the lava to go away, and jump easy-peasy. Not sure it's done like this, but it could be cool to have a game with an insane difficulty, but have to find the glitch to make it the easy way.
