I got the basic travel stuff down finally. Dungeons are navigable and feel great! Just throw in some enemies, treasures, and a boss then they'll be complete. I made things like pits you can only cross by teleporting, electrical gates that turn on/off in alternating patterns, switches that open gates, and booby traps that spawn baddies when you touch them. Next on the agenda is testing every door to make sure they lead to where they're supposed to. It'll also give me a chance to experience the world from a player perspective instead of a zoomed out tile map view.
