@chengchisang Hmm sounds like something bad happened to the tutorial the day before I submitted the last build. Will be working on fixing these issues tonight. (for reference I'm in Sydney, Australia. GMT +10 timezone.) As for roll/yaw, if you go into settings (top right in game, or bottom left in main menu) you can change it there. For the time being, anyone encountering tutorial issues: if it bugs out more than once, just skip the tutorial for now! Sorry for the inconvenience!!
