Algodoo

Rated 10 just because it's fun to mess with

"Press 1 to WINDOWS 7"

Ya, it would seem that on Algodoo, the loading mechanism needs to be "helped" a bit. Right after you fire, and it begins to move back, it doesn't move back all the way, so you have to pull it out a bit farther for the next round to fall in.

Very interesting! Is it possible you could reduce the flicker? (Like when it goes from 3 to 4, or maybe it was from 4 to 5, I can't remember.)
