Hi everyone, super new here and pretty new to trying to properly own/play with a Tamagotchi (I've had them forever, but mostly they were cute egg shaped keychains to me xD). I can't seem to figure out how to befriend/marry an NPC in my Wonder Garden. I have the zone unlocked and am bringing the item the Tama I want to befriend/propose to when mine grows up, but I have several questions, if anyone has the time to help me answer them.
My first question is, is it random chance depending on whether I get the Alice or the Mad Hatter character to play with when I visit, or does it change hourly or something?
Secondly, do I have to meet/play with them so many times as a child/teen before I can propose as an adult?
Will playing with both of the tama's make it so the one I want to propose to won't accept?
How do I know they'll accept my proposal, and if I fail in proposing, can I do it again later after interacting with them more?
And lastly, if I do succeed in marrying them, but say I don't get the genes I want, can I try again in another generation?
I'm sorry if these are weird/random/obvious questions, I didn't find anything that really gave good advice except which tama liked what item.
