About this game

PLAYTEST DISCLAIMER: It is very Early access. Proof of concept. There are UI bugs, known issue of soldiers running from villages, not user friendly yet. I have consulted with various play testers and watched them play and this playtest will be cleaned up in its current version to be more stable. Then i will focus on Player combat for the next update. You can definitely play through to the end at the moment. But be warned it does have bugs. Do consider joining discord to express any concerns you may have. This is the very start and i cannot wait to unveil more in the coming months. Cheers an have fun ! 

Hit Tab Key to open up debug menu , controls are viewable with button bottom right.
