I reviewed some random Wii Worms sequel a while back. I considered its biggest downfall to be its glaring lack of ninja rope, the endlessly satisfying tool that allowed you to bounce and swing your worms around the screen very quickly. I often thought that Team 17 should make a spinoff platform game centering on this mechanic. They didn't, but someone else did.
Let me be clear. Final Ninja is the finest platformer I have played in the last decade, easily. You can beat it in under an hour, but it's arguably the best 2D platformer since Super Metroid. Believe it.
Final Ninja is very simple. Use the arrow keys (or WASD) to move around. Down makes you go into a transparent stealth mode. Up makes you jump. Click the mouse to fling ninja stars; hold to throw your grappling rope. That's it. It's very similar to Bionic Commando, but the rope mechanics are much looser and more...swingy. Also, there are stealth elements, which do not interrupt the flow of the action, but complement it. The level design is impeccable, and the simplicity of aiming the single weapon and flat-out awesome ninja rope will make you wonder why most famous platformers weren't released on PC.
