The four commons are likely to be in the game, plus I really like the others you listed.
I will do my best to keep it simple. I would love to but I haven't received any form of contact from my teammate for almost two weeks now. I'd rather not have to do this all on my own.
I guess I for now unless my teammate strongly objects I will assume that we will be making a 2d game.
I will probably try working on the dialogue for the Yukkuri as well coming up with a few possible scenarios until my teammate contacts me again.
