Haha yeah, dunno, I never actually graduated as an engineer so I wouldn't know. :D But yeah, they probably were not supposed to explode that much but since physics can get weird I just went with it and let them die when there is some overlapping with the walls, too big collision forces or limb snapping which ended up resulting in quite a lot of destruction. And it probably doesn't help that I was the only person playing it during the development and got good/careful at plaing it. It's hard to make easy games :D
Thanks for giving it a go and leaving feedback!
