And that one just happens to be one of the most perverted =/
And does it have to be a flash game? Because I know this hilarious for a while game that is only a couple kb in memory...
Sumtori Dreams. Try it, it's a fun game to play when you are diehard bored.

pretty much all of the ragdollsoft games
here's the link

although they aren't really flash games

I dl'd Rubber Ninjas demo...
It would be sooooo much better if they made the camera angles better and things easier to beat... so hard!

It's actually easy. Play the first one if you can't handle the cameras swift movements. Just gotta combo tap ur arrow keys to make you spin around and hopefully land a few combos.

Yeah, I already beat the demo and it wants me to buy full version.
NOOOOO THANK YOOOOU.
The second time I actually beat each level in one try

Anyway, about the actual topic now...
I suppose this counts so here.

Nice physics games.I wasted a whole hour playing

A very nice physics game would be Armadillo Run (I guess this was the name).

i found a torrent for the full version of rubber ninjas, i dl'd it and i was immersed for about 2-3 hours, but it lost all intrest after i beat all the campaigns i could try to find the link for you but i can't really be fuc.....
