I know this was a one-page game, but I think giving more in the way of prompts would have gone really far, and more description of what good or bad values represent.

Also, the way it's laid out also feels very repetitive, with instructions being repeated for each slot, and the day taking up such a prominent amount of space on the card.

I feel this could be expanded into a fun, silly and maybe multiplayer game, with just a few more rules, but it's just too sparse as it is.
