This is a remake of a 2004 Japan only platformer and it shows. It's frustrating but in an endearing way that will remind you of playing retro classics. Very little is explained to you, you're told the controls then thrown into a game with no further help. The level design is deliberately unfair, filled with invisible pits and platforms. Lots of traps that will kill the player or force them to reset the stage. There's a time trial mode and grinding objectives in the stages is good fun, replaying the levels takes the bite out of their hostile design. If that sounds appealing, then you will probably enjoy this game.
