Damage was left on the cutting room floor, which was lucky because it showed me that bouncing off the asteroids as a form of steering is really fun XD. I'll probably find some way to include damage (along with enemies and more to do) in such a way that bouncing off asteriods comes at a minor health cost. Maybe I'll give you a standard "Hull and Shield" set up so that part of your health regenerates, making the small health cost of bumping and asteriod mostly negated by your shields. We'll see...
