In SOv3 or the next content update for SOv2 if Meiun gives up on SOv3 (not saying he should or anything), the areas shouldn't be left and right with some up and downward slants here and there (like mountain and grass hill), but there should be like areas in the sky or underground so you can go in all 4 directions ↓→↑←. Also, there should be split paths (one up, one straight or one straight, one down, ect) so that it adds variety to your choice of paths.
PS: Don't reply with, "Oh, Meiun isn't going to update v2" or anything like that because thats not what I'm saying and I could care less if he is or not (if SOv3 is still in production however)
Yeah Meiun has said (I think) in the past is that he wanted to make his game less linear. I think this may come into being on Stick Online 3.
But yes I agree, there should be more path diversity.
