I 100% agree 😄 To be honest, I don’t really know much about optimization yet or how proper asset loading works, so the graphics and assets are basically unoptimized right now.
Since the game was running fine for me even on an old laptop and on mobile, I didn’t pay much attention to it during the jam 😅
And about the screen size — there should be a fullscreen button in the bottom-right corner of the itch.io player, which should help it fit properly on smaller screens.
