Sorry for your loss, I had an aunt who passed away last year who also had dementia. I also understand we have all had a bad last couple of years (thank you covid). I wouldn't worry too much about the grammar, there are lots of games where it's obvious English is the creator's 2nd, or even 3rd language. Those of us who barely speak our native tongue have no right to complain about those who chose to develop games in a language other than their own, instead you should be praised.
My only issue was the time since anything was done with the game, but considering your losses it's perfectly understandable.
You need to take care of yourself first before taking care of the game.
