I had GC issues with the old blaze as well, after some profiling i found some unnecessary allocations and .dups that I removed for a nice speedup. Before i fixed those spots, the GC would get so beat up that it would just crash after about 8 seconds of collisions. I don't know how different Blaze 2.0 is from the version i had, but I'll take a look when I get a chance and see if I can be of any help. I'm using Box2D for the time being because there were still GC issues, but I'm very excited about "smoothed partial hydrodynamics" and non-convex models/partitioning.
