Sorry, I have only tested it on 1920x1080 settings. I still have to fix the mouse issues. You can navigate with arrows, UP/DOWN, LEFT/RIGHT, ENTER/ESCAPE, and E (for achievements, profile, runes). Also, the game is made for V-Sync (60 fps). Without it, it's too fast. Thank you for trying it out!
I made it now to be in a windowed mode, it should help. Also, I capped fps at 60, so you should be able to have a proper experience. Thanks again for playing it!
