I played some. It's not really my cup of cocoa, especially sine it's really close to Monster Galaxy. The fact that the starter Kin are soulbound did not help.
I did manage to sell the Kins that I no longer wanted (i.e. the soulbound ones). Now, I have a Cubdrop and a Coral Cubdrop. My current goal is to obtain Neptune the Seapony.
I also hope to evolve both of my Cubdrop into Cubchew...or whatever the evolution is called.
