Short update:
INVERTED 2 is still being made, less progress has been made over my winter break than I would prefer. Despite that I expect to get really early copies to some irl friends fairly soon for testing and feedback on the new mechanics and levels (as they're made). I still need to pound out levels and art assets but I feel like that will probably be the easier part for me.
And just for a little thing: a (mostly) working main menu mockup:
(The default Unity menu sprites will get replaced.)
