A fine-tuned Flash platformer about being an acrobatic ninja. Seems like it started like a take on Lode Runner since the goal was to pick up as much gold as possible, but really has its own character thanks to a striking aesthetic, a satisfying wall-jump, and great level designs. I should have been way more into the platform releases N+ in 2008 and N++ in 2015 - especially since they added co-op - but nobody else seemed to be that excited about it and by then I'd played the heck out of this game. I also learned a bunch from their few blog posts on how collision detection for the game was built.
