This is a great game and I really enjoy it, but I found some problems when I played it. I finished all the character events except Kali, and I always maintain a 35 range. Is it right or how could I fix this problem?
Guessing by "maintain range" you mean Friendship value (aka event counter). As Runey said, check the wiki. That woulds tell you her next event starts automatically in the Lobby.
35 was her limit for v0.13, that could be why it had stopped there. The current version is v0.15, if you'd like more content.
