Neat idea for movement! It sort of felt like I was controlling feet! I was a little hard at first mapping the colors to left and right. I also made a game this jam that used the Hinge mechanics and I can appreciate the difficulty of balancing the different physic components
Thanks. The hinge joints were a bitch to get right. If I increased the number of velocity and position iterations then the mechanics would run accurately but the performance of the game dropped drastically. And if I kept the iterations to minimum then the chain broke off on increasing momentum. I had to spend a lot of time testing to find just the right amount of iterations.
I have downloaded your game. Will play it soon and share my thoughts.
