Gamifying everyday tasks is often overlooked but can be so helpful for people dealing with things that may not be obvious. So I think your theme is already a good idea, especially since so many solo rpgs may focus on the experience or emotional realm. 

For your game page, I like the colors, but the white font on such a light background is a bit difficult to read. Which is a shame because the color scheme IS nice. You may want to consider choosing something closer to what you have for your game document, make the white text larger, the pastel green darker, or just make the text a different color altogether.
