8 squares, 756 seconds. well done. Was about to ask about the music then I saw "1024bytes of code" and daaaaaang.
Thank you, looks like you got a good time! I would have liked to include at least some sound effects, but even that would have eaten up space fast. I'd like to make a more fleshed-out, non-size-limited version of this at some point, I just have to work at limiting my scope (a big reason I started size-coding in the first place).
Oh also, they're technically power cells (yeah, I know they're squares, but Metroid gets away with it. ; )
