Evolves on Spelunky HD's ideas in tons of creative ways. Super fun to play and (attempt) to master, all the new levels and mechanics and everything are great. It is punishingly difficult though, even more so than the original, and my one genuine gripe with the game would be that sometimes the level generation can give you a level that's actually just bad, which isn't something that really happened in Spelunky HD. I suppose the more sprawling, complex levels leave more room for bad generation, compared to the more simple levels of the last game. Still, a whole lot of fun, and one that I'm sure I'll still be coming back to for the forseeable future.
