Good job either way! Jams can be difficult, you'll get it next time. As others said, I got left in a closed room. In another revision you can check for these rooms and delete them or choosing not to spawn the player in them. The dungeon was good, although I would increase visibility or give an item to do it. Also, it felt a bit empty, even getting some enemies and items spawning at random would go a loong way. You can also draw a few different tiles to get some variation in. Keep at it!
