I actually think the older art has a certain charm to it. The newest stuff feels a bit too polished. Its overall a lot better sure but I think the art could still improve as it always has. Which is to say the only issue I have with the game is that there's not more of it.
I really hope other people take this as inspiration to make their own works. Finding something like this is simply impossible. With the closest things being not at all the same even if they themselves are good.
10/10 game because its got no competition. We need more.
