Looks absolutely wonderful; good docs, clean, no extra BS art assets you're not going to use, just some quality functionality and mechanics. After the holidays I'll probably be picking this up. A question and couple of feature considerations: I'm assuming people who purchase the package will get free updates as / if you release them? Functionality considerations regarding two/one wheelers: -- A "balance" mechanic, say when landing off axis from a jump, performing endo/manual's or unicycle type balance points. Perhaps just an option for it? -- A niche feature, but perhaps a "grind" trick function on two / one wheelers, for bmx / unicycles or similar. -- Perhaps it's beyond the scope of your intent, but rider crash/ragdol, or rider implementation in general. Again, your work is fantastic and I look forward to getting my hands on it, once I finish up buying my peeps their holiday toys . Demo alone is so fun.
