I'm personally really excited to see all the different world themes! Thus far we have the Green Tropical level, the Cave level, and the concept art for the Snowy level and Swamp level. Do these levels have names yet?
I know it is very early on in development but I hope that the dirt paths shown are for the NPCs and not to guide the player. I think they should play up the exploration aspect of this game as much as possible. I also think the 'blocky' aspect of the design everyone is discussing might make it too clear of where to go whereas taking away from the exploration element of the game that is so important. Just my opinion, but who knows! I trust this team to do what is right. For all we know the 'blocky' aspect could just be that one level (if green tropical and cave are the same) and the others might not be 'blocky', right?
