Lol, I really like the story about the homebrew scene. It reminded me of people tracking down those mobile-only Mega Man Battle Network games locked to old Japanese flip phones. Great premise, and a smart take on “Old Gold” for a homebrew jam.
There was something really hopeful about the chord progression in the music. I kept expecting it to build into something bigger, because that’s where it felt like it was heading.
I also like the idea of a sentient Game Boy. If you wanted to ham it up, you could work in accessories too. Maybe it gets a Game Boy Camera to stun enemies, or uses a Link Cable like a whip.
One small art note: the eye shape reads a little like a skull socket, which makes the Game Boy look slightly ghoulish. Rounding the eyes out might make the character feel friendlier.
Funny game, good entry.
I drew over the eyes to show what i mean.
