This is such an amazing concept, and the execution is nothing short of perfect. I can't really see anything that you'd need to fix with the current iteration. However, as others have said, it's not quite as fun to build the level and play it yourself. I think this kind of thing would be perfect for asynchronous multiplayer. If you added the ability for one or more controllers to be used while the keyboard master makes the dungeon, I think it could be great here. Just spitballing ideas, but perhaps allowing the dungeon master to set off traps while others are running through it or having a mode where the dungeon builder gets a head start and the others then start running while he continues to build the dungeon ahead of them. Either way, great entry and for sure one of the coolest ideas in the jam!
