Really impressed with the scope of what you attempted here, just a shame you didn't have enough time to complete it.
The music "editor" was clever (especially with Pico8).
Plus I loved all the hidden/special menu items and the effects they had on the game and UI.
Look forward to playing again when it's finished (e.g. post-jam) - IF you plan to come back to it, that is.
Great stuff, as always. :D
Thanks Paul! Yeah my interest got a bit trapped into generating sound & music at runtime with Pico-8. That's definitely a thing I'd like to dig more, and how I can make it keeping its tempo to begin with! The UI was fun too, esp. with the focus of losing the player... :D
