Patch NotesOfficial
Patch v1.0.2
Several changes and fixes in this update: GAMEPLAY Changed the 'Incapacitated' option 'Return to castle' to teleport your character to the castle immediately instead of waiting for the next turn. When your character is returned to the castle (via 'Incapacitated' options), your character now drops half their gold instead of all of it. Steam leaderboards are now updated more frequently. Fixed issue with moving/interacting on some occasions where it might say 'Not enough space' when there was. Fixed issue with being able to interact with chests when your character had no path to reach the chest. Fixed issue with not being able to remove quest items from chests. Fixed issue in one of the scenarios where you able to talk to the King at a time when you shouldn't be able to. INPUT Swapped the camera rotate keyboard keys around (Q and E) to be in-line with the mouse controls (middle mouse button). UI Added more info in the Settings -> Keys about camera rotation and object interaction. Added more tutorials for camera rotate/zoom, levelling up and running out of Action Points. Added even more instructions to the screen after creating your character to inform about camera rotation/zoom, interacting with objects and how to start the next turn (for those who didn't read the tutorials). The instructions disappear on turn 1. Fixed shops/chests displaying "Encumbrance" for your character when the scenario option 'Use Encumbrance' was turned off. Fixed a typo in one of the tutorials.Read full article on Community Announcements (sean.craig)Patch NotesOfficial
Patch v1.0.1
Some minor UI updates in this patch. Please submit any issues you find or changes you'd like to see. Thanks for playing! UI For those who didn't read the Tutorial at the beginning and get 'stuck' in the castle, some text is now displayed on the bottom-right of the screen telling you to click the "Ready" checkbox to begin the next turn. This will open the gate. The version displayed is now the intended version (forgot to set it to 1.0.0 on initial upload).Read full article on Community Announcements (sean.craig)AnnouncementsOfficial
