So far I've not gotten to any major point but I have only been playing the mobile version so perhaps others are not having this issue.
Currently the game crashes my phone each time I get to stage 2 of "purple magic's" story
Asides from that the game has been running fine but I do not think I'll be able to gain any further progress if this continues and would like to know if others are having this and their potential solutions, that is all for now.
