Heh, don't worry. Most hamsters aren't locked behind choices and you should be able to find them just fine. It's only 2-3 that are, I think.
If you want a guide for your search, feel free to join the Discord - there's a list of hints for all of the hamsters on there.
I understand. We all have our dislikes and there's not much to be done about it. It's fine. :)
Eh, CH playing in Japan is based on some early misconception on my part, mostly. Same with CH playing in a "school" and being named accordingly, to be honest. CH being my first project of this kind had me make all kinds of mistakes early on that I now know better. Any future project will (hopefully) profit from my learning experiences here, though.
