oh my, I think you just fixed the crashing issue, I was using box2d asm.js for the physics engine. After switching to box2d web, the crashes stopped! I have no idea what's the difference between the 2 engines, but they seem to look and perform the same (by eyeballing).
thanks for the original demo. It's really awesome. I was just exploring that construct 2 can do, so was fiddling with various tutorials and plugins.
that's a pretty awesome adaptation you got there! I have no coding experience, your capx looks really impressive. Looks more like actual C code than construct 2 lol. I tried it on my mobile and indeed the performance is super sluggish where as it worked very smoothly on the desktop. Do you know why that is?
