Haha, graph paper! I personally love manual mapping. It (and still is) a big part of the full traditional dungeon crawler experience.
Hehe yeah I know a lot of people hate the invisible teleporter so I thought I'd make it a little bit less irritating - perhaps :D
I'm really happy you enjoyed playing and your kind words are much appreciated :)
The AtlasCreator has been an amazing tool for this project and I will keep improving on it and definitely make more games with it.
