I have compiled a list of questions I think we would all like to know!
The second screen on the status window - These are grade scores, do they have any effect on anything else in TamaSuku (such as which characters you get).
When special characters like the king come, what does that extra dialog mean, what are they talking about? (I don't have it yet, therefore cannot read for myself)
Why did one student give me a present and not any others before him?
When you press the "C" button, while no icons are lit, the character on the screen will get a ! by his head. Sometimes the character will be happy, other times sad. Why is this happening and what does it mean? Perhaps it is like waving to the student, or poking them, getting their attention perhaps?
Why do the characters come to me out of order?
Does TamaSuku ever end? Like Tamagotchi go back to their home planet. Do TamaSuku students graduate?
