Hey! Lovely work, the vibe is really great, and it's a really unique take on not only the theme, but also how you're using music to build up your game and create a sense of progression and player identity. Too bad there wasn't enough time to look into the other systems as I feel they'd have expanded the gameplay loop a lot and given more incentives, but I think this is already a solid take on the idea.
Great job on this year's GMTK. Abraço!
