2D Physic Engine what perfermance?

Nice job Frank, it seems you do some nice progress :slight_smile:

@robinmaypanpan The performance in C are not the same as on PC. C is more performant than Lua but both will not run as fast as on PC simply because it is not reliable to emulate the playdate performance in the simulator.

As Nino suggested, the best is to share playdate builds so that people can try and record it.

For reference Dustin already ported box2d lite on playdate and this is pretty fun to use in a game even though it can handle only few objects at a time.
