Regarding local event handlers not working on export to DAAD, one of the DAAD guys mentioned that in one of the previous game jams, so I stopped using them. I now put all event handlers in the global event handlers. The only downside is that you have to do an is_at test where appropriate. The upside is that all my event handlers are now in one place, so it's easier to manage.
Question for Chris: Is this still the case? If so, it might be worth mentioning in the guide on 8-bit export, assuming it's not already in there.
