Here's a nice little platformer. I actually played this without reading any instructions (as I usually do!) and at first I was quite shocked about how good the enemy AI was,the neat random decisions it made about jumping on other platforms, but then realised that the enemies simply follow my movements, millisecond for millisecond. D'oh!
That's pretty much the game though, you get a set of platforms each level (which are scrollable too) and you have to collect all items. Then the last clone that has been spawned (which is normally dark) turns exactly as your sprite and you have to touch it in order to finish the level. Of course that's not too easy with all the other clones hunting you down! So, clever navigation and strategic pauses are a must. There are some zones that either make you go faster or slower to keep things interesting.
