Thanks! I'm not entirely sure how much work it'll be, but looking at examples of pixel art drawing programs in Godot did make me realize I might've underestimated how difficult it'll be, haha. Luckily I don't need to work or study rn, so almost all my time can go to jamming out!
I didn't actually intend to do a retro look at first, but the palette I ended up using in Aseprite was the NES palette, so together with my fairly basic pixel art skills it ended up looking quite retro indeed :p
