Your swamp map is a total mess. The walkable path is very unclear and there isn't any sign to indicate which is the correct way. There isn't any short cut to the next scene after beating the heron mini boss, and you have no idea that a boss fight is waiting for you after touching the mist door without any confirmation of hints. This is perhaps a bs design, but not all the players can get it at the first time. Then you lose all the progress (thankfully there is auto save) with very low health, and have to walk all the way back to collect all the items. And a sign is missing at the entrance of the swamp so you cannot teleport back if you accidentially run into it. And you don't know where is where: What's the place I'm walking on even called? How can I know its name?
It's stongly recommended to polish the teleportation/map system to give the players a better gaming experience other than time consuming nonsense walking, with little interaction with the itmes, environment, characters, etc. Anyway given the fact that game is still in development, it's still an epic demo with full-ledged plot.
