Just a small update; 
I've added a settings page to the pause menu with a slider for adjusting the mouse sensitivity of the camera, so hopefully that will be a fix for people who were unable to play due to the mouse sensitivity being too high!
I've also made a WebGL build so the game can be played in the browser, rather than having to be downloaded, but the Windows and Mac builds are still available for anybody who would prefer that!
Thats all! Thank you!
