As the guy who made basically all of the art assets for this game.
That's kinda just my personal art-style, could the colors be a bit more muted at times? Maybe. But it's already hard to make like 70 sprites from scratch in ~4 days, especially seeing as I'm not a very experienced sprite-artist.
As the guy who made the soundtrack for this game.
Thank you! I put a lot of effort into every single track!
