Sorry to hear that, could you tell me which version of Windows you are using so I can try to debug it?
Also, can you try to press TAB and see if a menu pops up? Maybe the brightness is just too low? It might also just take a bit to load, maybe wait a minute?
If nothing works you could try the browser version here https://no-context.com
My version of WIndows is 10 (about my brightness, she is high all the time), i will try to press TAB to see this and wait a minute too.
if this unlocks the game i'll let you know
