Hi Colin, thanks for the feedback.
For 1, It appears I did actually forget to remove the mouse cursor locking I had for a first person camera initially. It should be fixed now.
For 2, I've added a few more resolutions to the file. also for reference what would a non awkward window size be?
For 3, I didn't realise people actually read the readme file, and also the reason I included that bit was purely because I hadn't gotten around to including something that reported what caused the crash. Both the page and file should be updated now.
For 4, I've updated the camera positioning a little, it should be better now.
