I haven't played through the entire thing yet (just completed World 1 so far) but I think it has been a pretty poor episode so far. I admire that it can be creative in many areas, the music selection is nice and the level titles are great. However, everything else just felt flat to me. The level design isn't absymal, but I do think it looks ugly and unpolished. Plus, it has some kaizo-related problems such as guessing which invisible block to hit in order to continue with your path and using a bullet bill to advance. (there's also a section where a bunch of bullet bills come which does come as unfair).
