Yeah, after completing chapter 3 they said you'd have freedom so I pretty much went exploring and grinding and stuff. Honestly I meant to continue with the story sooner but I was like "When im level 20 i'll continue...okay 30....okay 40" xD tbh I'm not sure when I'll go back. Maybe when I hit 50 or get 4million so I can buy the last skell right away cause I'm at 3.1million from mining and missions
