Holy shit, what an absolute joy of a game. This is perfectly up my alley, instantly snappy movement, simple controls but a lot of skill involved, single screen and arcade-like. The levels here are so creative throughout, it could have gotten away with so much less, or with reusing concepts more, but there are amazing level concepts that are used once in a level you can beat in 10 seconds and I love that. The pace of this was enthralling and kept me going through the whole thing in one sitting. The last world in particular was a blast, it does get tougher but it's not just a challenge of existing ideas, it breaks all of the rules and pushes the game to its limits. Damn, what an awesome surprise this was. Go play this right now.
