Nin2-Jump could well have been a flash or web game, as its visuals are not very remarkable, and it has some problems in control which may be annoying sometimes. But it also has something especial.
The first platform made in Cave seems to be a successful project. Gameplay and a high-level graphic design offer a positive assessment to the game.
A memorable presentation and well-crafted stages make this quirky platformer fun for the fleeting period of time it lasts.
Nin2-Jump is an interesting experiment, with gorgeous graphics and a cool main character. Too bad that its level design and some weird choices from the devs made the entire experience a little nightmarish.
