The control scheme is really cool. I enjoyed using the mouse input to control the stick ingame. This made the experience way more immersive! ^^
Also very big fan of the dithering shader and the art style.
Small issue: When tabbing out once and clicking back into the game, my mouse becomes visible and is limited to my screen. Therefor, you cen't rotate and look fully any more.
Great submission, tho! :3
