I just finished the main story in boneworks. Took me 7 hours, mostly because I was fighting gaben's shitty joysticks, and a bug in the between-level warps forced me to replay the entirety of the warehouse level (really short thankfully).

It's weird. On one hand, the puzzles are really simplistic or annoying, combat is easy, plot completely forgettable, dude melons lmao. On the other hand, it's still a pretty sweet engine, and climbing around lightly tapping things with a hammer until they break is fun in some primitive, autistic monkey brain sort of way.

 I hope they release a level editor or official mod support. Or hopefully hammer 2 with HL:A has the same level of physics interaction and modders can take off of that.
