Nine hours in and I’ve got a basic inventory system working where it display items you have collected in three columns and you can move your selection over items. Can’t do anything with them yet, but I plan on reusing the action selection system for that so it shouldn’t take too long to get done. I’m going to get some sleep now though, it’s already 7 am here.  Hopefully I can get a lot of the content into the game when I wake up, then the last day I can spend on polish.
