This build sees some great performance improvements! I've rewritten the game internals to be multi-threaded (rendering and simulation now run completely parallel with the main thread) so that it can make better use of multi-core processors, and the game no longer have any problem with keeping a steady 60 fps on modern devices.
There are also stability improvements, and I believe I have fixed a couple of crashes from the last build. But moving to multi-threading is non-trivial, so I might have introduced some new ones. If you see anything suspicious, please report here, thanks.
