Loved this game! It really brought back the Motherlode nostalgia for me! Amazing art and intro cutscene. The music is chill, fits the vibe. As someone has already mentioned, the font in the store and the "core" in the bottom left corner have subpixel shadows, so it would not be possible on an actual GameBoy display. Otherwise, great job!
The art compliments mean a lot coming from you, thank you !
And yeah I spotted and fixed so many little things that did not want to stay in the display resolution (like the particle shader, oh god the particle shader...) but somehow the font ended up 1 px too small and with a weird half-pixel offset. Oh well.
