Void Ninja is a procedural free runner in the sense you are always moving forward, moving or tilting your head left and right, ducking and weaving around blocks, using Katanas to Slice enemies, a gripping and sliding motion to turn, two fists thrust downwards to jump, hitting buttons, walls to climb or slide along, hook shots to swing on, bullets to dodge, and my personal favorite a Bow and Arrow to get those pesky far away baddies.

While I had a little bit of a struggle to get used to the jumping and turning motions, once I got a better hang of it I was able to get through the levels with ease. With the turning motion I found if I didn't reach my hand out far enough I would grab my Katana instead of turning leading to my death and I found with the jumping that standing straight and using my head to strafe by tilting was the best way to ensure consistent jumps as going at it from an angle occasionally caused falls and frustration. 

Visually the title looks rather basic with some nice retro appeal, the enemies are untextured and there is well, a lot of yellow. I don't mind the style overall but would love to see more. At one point while playing I was thinking it would be cool if there was a blue and red katana and enemies to go with them to make the Katana parts a little more challenging and fun.

 I found the level editor a little daunting at first but I can easily see how someone could craft something awesome like the example level. If your willing to make your own levels this has serious excite bike level editor vibes too and I can easily see someone spending hours making the perfect levels to play. 

In conclusion I found the title to be entertaining engaging and offering a fair level of challenge with checkpoints. I enjoyed using all the different elements of the game especially the bow and the hook shot. It has great music, a cool level editor and because the levels are randomly generated it offers good replayability. The aspects of the game I wasn't so hot about really came down to frustrations getting used to the turning and jumping parts. I also found the graphical style to be lacking enough variety and detail to keep my attention for long play sessions. Its a fun game and I think its worth playing.
