My thoughts on the game so far is...
1. You'll gain too many quests and lose track on what you have to do.
2. You'll probably not realize you can adjust the size of the screen by clicking on the window borders.
3. You -will- get confused with some quests, ie. you need to "Activate" certain on-field items with an item in your inventory to make a quest monster appear - and the quest log doesn't really tell you this!
This "sign" system changes your character's capabilities each day: observe the bottom left.
Love = Matchmaking system whatever.
Battle = Criticals, etc.
Work = Life Skill capability (eg increased chances to make items/equipment)
Wealth = Monies
Agility = Dodge rate, avoid Crits, etc.
