(Review originally posted on ggapp.io)
A master class in platforming level design. A must-play for anyone wanting to go down the list of "video game enthusiast canon". The gravity system is fun and even elevates the game's replayability by inadvertently encouraging speedrunning and even the often-maligned motion controls give the game-feel a sorta natural rhythm that just feels smooth. Even the recycled content (Seaside galaxy and such) is generally changed enough to be fun and not noticeable.
