This is stellar, you nailed this absolutely, take my money plz-
I have no words for the music, it's just stellar bgm for a game I wish I could play! Landed the aesthetic handily. Really nice well thought out concept too, probably the most crystalized concept I've seen all jam.
Also that COVER ART is PERFECTION and I wish there was a category for it, because this would win that category EASY
Also OpenMPT? Absolutely based.
