theres 2 problems with the gun, the bullets fall off the shells before it can fire them and the mag falls out alot. other then that its a really nice gun
It is possible that phun works differently than algodoo seeing as phun is free. The flywheel is sort of supposed to do the pulling, the piston is just there to keep it going.
I was just tinkering around when I made this after a few attempts before that failed. I plan on making more engines that have higher torque and less massive flywheels. This is just the beginning of a large series of engines.
