Mystic Belle's Beta branch has been updated with a new build, introducing some pretty radical new features.
First of these is the introduction of the difficulty select at the start of the game. The player will no longer be able to flip the difficulty at will during gameplay, as the modes are a bit more different now.
Second major feature is the addition of warp chests. These are only available on the easier setting. The chests allow you to store up to 14 inventory items in them, which will be available in all other chests around the game's world.
This should resolve at least some of the woes caused by the game's limited inventory space, as anywhere you go, there is likely to be a chest nearby.
