Oh no, not nearly completed. Hence the "Demo" and v0.03. I really just wanted to gauge people's initial reactions to the idea and get any immediate criticisms and flaws, such as yours, out of the way rather than waiting and having to upturn the entire game halfway through.
I know that my mapping isn't the best around, due mostly to the fact that I'm not very good with minor details, like scattering vines and shrubbery and decorations and whatnot. -_- It's not that I don't know what to do, I just don't have the sense of style for it. But I can always practice up and try to improve the current and future maps from here - thanks for the commentary.
And if you didn't actually download the game, bad screenshot selection might also be a fault of mine. I didn't pay a lot of attention to it before, but a number of the map screenshots look like they were taken in areas where two maps meet. The game transfers between maps without any fading, so the first 10 pixels of a map are limited in that they can't include any tiles that aren't in the adjacent map's tileset.
