I didn't know which version of the game I should play so I just went for the latest one (v0.03).
It took me a long time to figure out how I was supposed to use the arrow keys to control the fishing, especially since if you don't do anything you still gain sanctity points, although at a slower rate. I tried different buttons, I tried mashing, I tried slow tapping. Eventually I got it to work though and I won the game.
I liked the idea of the colour returning and happy audio starting to play as you began to feel better.
There were some very good philosophical concepts in this game but clearly you needed more time to implement actual gameplay. I would have loved to have had a few different activities to try out and maybe some interruptions that pull him away from that feeling of sanctity (life getting in the way of happiness) so that there's some conflict in the gameplay.
