Hey Ollstar!
Yes, updates are always free for anyone who purchases the full version, regardless of when they buy it.
I don’t really have a timetable for updates. There were 10 updates released in the past year (as it was still early in development), there probably wont be as many updates this year, but I’ll be gradually adding fixes/features.
Hand tracking is included now, but it only visually tracks hands. Scene changes are all still made using controllers.
