You aren't the first Dev I know who has lost someone, and won't be the last, and I will always say the same: Take the time to grieve. A game is not worth more than the time YOU need to find some peace after losing someone. When you are feeling ready to work on things again, great! Until then, take the time you need. Take care of yourself, and we'll see you when you come back! My condolences to you on your loss.
Sincerely,
Scott
