Such a nostalgic vibe! I’m with Atremic on the Z part—since W isn’t used, maybe just map both letters to the same input and you’re good to go! The Windows build bugged out on the last screen, but I did reach the ending in the HTML version, so I still got to enjoy the outro music :)
Loved the music and the art! I’d definitely play more if there was a bit more polish and juice on the controller and a bit more content. Great job!
