This was really cool for me, ball games whether they be droppers or like marble games i feel always have a kinda chill vibe to them, and associating that with vaporwave makes sense to me. It works well with the PC windows in game, and i had a read of your other comments about cut ideas and man, i wish the jam would of allowed you some more time on this, i would of liked to of seen extra windows with pop-up minigames or a window with a third person camera, those would of been great.
I liked the upgrade system, it was mysterious and esoteric. Yes glam me with up Gems and Cheese please. And again your idea of taking damage making you lose pieces would of worked so well.
I Genuinely think you have some really cool ideas that could come together to make something mechanically interesting, so naturally you're getting a follow so i can see any of your future work :D
