Thank you very much for your detailed review! It's very telling that you completed it twice, with the unintentional "victory lap" music. A.K.A.: the bug where the boss music persists after the fight is over lol.
I know many people say this about their jam titles, myself included, but this game definitely has the highest chance of being developed more after the jam is over, so i'm glad that you expressed that same sentiment!
Side note: Tetra Ho! is great and unique and i hope you work more in it, too!
