Small bump. I've been testing it with my guest account and realized these three errors:
1. Dollar sign being way off (in the shop where you can sell your shells; also happened to other text parts inside that NPC)
2. "You're" instead of "your"
3. 'Up' and 'Down' arrows displaying small notifications are on the very left next to the map (also been there during the tutorial), while on my other account (having a gold subscription) they are on the very right. Not sure where it is supposed to be but either one seems bugged
Else it does look very nice covering the very basic stuff. Maybe you should also explain how you can earn more HP and cover some other stuff you come around pretty often (sparring, strafing, hotkeys etc)
