Thank you for playing!
Sorry to hear the camera movement made you nauseous. Was there any delay/input lag? When I turn on the alternate v-sync on my end it kind of adds a motion smoothing effect to the cursor position, I can see how that'd make one nauseous. I thought about maybe adding a slider that controls the camera speed, but having instant movement is kind of needed for the combat.
My highest priority is definitely going to be improving readability, it's easily the thing that needs to be worked on the most. Thanks for the feedback and kind words!
