I've been playing this completely addicting game for the past few hours, over the course of about a month. It's called necroCave, and it has the exact same (if not better) physics of a similar helicopter game, however with better controls.

I've been playing under the alias "Shadow" for a while, and my all-time high score is 2559.
You might wonder what's up with that seQuel character. I don't really know, but every night, I'll end up with the top score, and 5 minutes later, he'll have something in the 2700s.. meh.
NecroCave, bitches! (Addicting)
What's up with the blue line?
It seems to be a two player version. I can't control both simultaneously very well.
Yes its 2 players, but it will only take players high score and not the combo from the 2.
