I added an encounter with an NPC (in this case he's a rectangle, placeholders right?) where you can talk to them to get instructions on what to do. I've also added two types of events where Ella has to repair a door and a gap in the floor to progress. Bear in mind there are likely to be bugs in this build but I just wanted to get a core idea on the screen before I refine it down.
Here's the mechanics build so go and check it out!
