Just gave it a whack. Runs pretty well. Averaging about 40-45 fps on my LG G2 when doing physics related stuff. Definitely cpu bound as when I’m not interacting with stuff, or stuff isn’t moving, it’s a solid 60 fps. I wonder what the performance would be like on something like the Ipad Air 2.
Controls for moving around seem to be rather iffy though.
Oh god, love the moon gravity cars. Now, if only there were some buildings to knock down too. I want to run some random block into a few buildings and watch them fall all over. Of course, I think my device would choke, but oh well.
