Lame controls, not much value
First of all, the controls. The characters movements are slow and awkward, and the jumping is very weird. You only have 3 angles at which you can jump: standing vertical jump, running jump (one angle), and running higher jump (higher angle). If a ledge is in between these angles, you just cant get there.
Second of all, value. You only get one level, which gets old after a while. You do have free roam, but the actual movement is painstaking, so its hard to get to some parts of the level and youll end up just playing the same parts of the level over and over again. You can get more levels with an in-app purchase, but you should really get more than one level without paying extra.
While it is true to parkour with the various vaults and such, it lacks the fun of running around at high speed that real parkour has.
