I've had dreams like this game. If Oculus-Supported in the future, then a definite must-have. If anything, just freerunning in the Freestyle level.
Want this game to be easier, or Freestyle to be more fun? Play some AAAAAaaaaaaaaAAAAAAaaaaa!!!! (For the awesome) and learn how to fall (as in, learn how to aim your falls, especially at/beyond terminal velocity); and achieve the highest Ninja achievement in this game (the first level helps to learn), and it'll be a level you'll lose track of time in (didn't realize an hour passed while inside Freestyle until I wrote this review/recommendation, and saw the in-game clock).
Being a 300/kph ninja that doesn't hit the ground? It's possible, and fun as hell. I can't wait for Oculus-Support for this. This is a pretty underrated gem.
As a suggestion to the developers (if still active), we need the ability to make maps. Although the vanilla set is fun and all, I want to check out other maps others would make, or come up with my own crazy-♥♥♥ parkour maps.
