Simple and fun! Miko looks really cute here!
I think the below comments have already pointed out what I wanted to say for the most part, but just to add on, maybe you can also have some optional taiyaki's that holds buffs/debuffs, so players holds a little more control over what buffs/debuffs they get.
Also, maybe more variety of buff/debuffs? Something that is more obvious to players, like longer/shorter table where you gain/lose a lane, controls reverse debuff where every 2 of them cancels each other out, decrease/increase visibility on the bottom of the table etc.
