If game is not launching on Linux or launches to unresponsive window, try removing "prefs" file from "home/.config/unity3d/HuniePot/HunieCam Studio" and relaunch the game. If still doesn't work, open mentioned "prefs" file and edit lines with "Screenmanager Resolution Height" and "Screenmanager Resolution Width" to match your display resolution, for example:
<pref name="Screenmanager Resolution Height" type="int">768</pref>
<pref name="Screenmanager Resolution Width" type="int">1366</pref>
