or download it from some sites.
It's called "n", it's a simple but cool flash game, and also pretty damn challenging...in fact, it's the kind of game that sometimes you go on playing just out a feeling of spite you generate towards it, the whole "you son of a bitch, you. will. not. beat. me!" deal...you play a ninja, you run and jump and bounce off walls...etc...while collecting timecoins, acticating doors, avoiding traps and deathbots. Controls are relatively simple (arrows and shift for jump on mine), the wall bouncing thing is pretty easy but needs to be practiced.
The traps and levers n stuff you interect with all has a learning curve, with more than one way to complete each level.
Simple, but very nicely done flash animation.
Just thought I'd share, I'm sure zwoti'll love it...
