Well it has taken much longer than I would have liked but it's finally over. I now have a level editor giving me a full set of actual tools for creating content. Which means I can finally go back to building and improving on the actual game!
Before that however I do have to tweak some of the routines that load resources as some formats had to change slightly so that they could be loaded into editing programs. But once that's done we're back to my original goals which were to make animations for the player and start creating objects to be placed in levels. With over 5 days still left in the jam I think I should be able to at least make one polished level and then finish the rest of the game post-jam.
