Hehe, the giant Grove in that preview looks kinda silly to me without the rest of the world appropriately scaled. Once that's sorted it would probably look a lot less like scaley Ao Oni.
Perhaps as alternative you could zoom in the 'playzone' a bit more as there was in certain rooms (slug nest, for example) in current game?
Just my twopence. With how quality the current game and Prowler is I don't doubt that you guys are going to keep nailing it!
