I tried to play the game but it not working
Then re-download Matriarch. Sometimes Itch slips in bloatware into the download file and such. Either that, or you have to babysit the download. My advice is compare the number Megabytes(MB) to the ones on Itch. If you see a number higher or lower than the actual number on itch then either two things have happened. Option (1) it didn't download completely Option (2) you have extra bloatware meaning either way you are going to have to re-download it
