Thank you! The belt extension was available at first, but it caused a lot of bugs, so we removed it. And for the reverse thing... We have the code that checks for "impossible" rotations and disables the factory if they were found. But we decided that it would be more fun, to let players still play the game even if they messed up the connections. The game is hard on it's own.
Thank you for your review I'll play your game too later
