Thank you for your compliments about the game!
We have a pdf player guide (link
) but it does not contain any key mapping.
The keys we have are visual in the settings menu in the "Keyboard"-section.
To change skills in the skill bar, you simply drag and drop skills from the skill tree into the bar. You can do the same thing with items. Open up your inventory (default I), press the misc section of the inventory (to the far right). Drag the flare to the skill slot you want.
We will be sure to work on a key mapping to add to the player guide pdf.
Thank you for your feedback!
