This is one of the most unique and intimate games I've played. Thank you for sharing something so personal and I'm very sorry for your loss.
As a game, the choice of music and the mechanics are particularly outstanding. I felt frustration and despair when I would repeat a level. At first, it didn't seem to make sense. But I also felt encouraged and stronger every time the level was overcome. If these mechanics were meant to represent how you felt during that time, then it translates really well.
My only suggestion is about the text. I found that the text tends to disappear too quickly, especially during the Anger and Acceptance stage. Maybe you can share the game's story in a separate text format or as a devlog for those who are interested?
Thanks, again.
