Very nice game with good artstyle, characters and story, the base gameplay loop and quest design  are enjoyable. 

Unfortunately the time mechanic is kinda tedious to play around. Time passes way too quickly, making it easy to miss events and having to wait another day.  Grinding certain materials or relationship points (especially for nel and slimegirl) is constantly interrupted by having to go home.  (This is especially bad since getting to combat areas passes a lot of time by itself)

The only way to circumvent this is by crafting energy potions, which again requires grinding for either mushrooms or money and constantly chugging potions, replacing one tedium with another.

Fixing this is simple: Make less time pass when moving around areas, keeping the flow of the game.
