I'll probably get downvoted, but I don't like Bjorn's route. It's clearly underdeveloped - it's almost entirely linear and has Arvo acting on his own without your input.
Also I just don't feel the chemistry between the two.
It's like... Bjorn is just being sad and barely saying anything, and Arvo's like "Omg omg omg, a bear! I want to cuddle him! I'm so horny!". Seriously, everyone else in every route has a game on. Bjorn does not, but Arvo is falling head over heels for him, it feels weird to me.
Bjorn needs a friend, not a fuckmate, what are you doing, Arvo? :\
