The design of the game is phenomenal however, my experience has been horrible because of the constant network crashes going offline every 10min and kicking me out to log-in screen. The game should have an offline mode if it's this unstable. 

Second. There needs to be a tutorial or at very lease a manual to explain how to even operate the game. Doesn't need to be hand holding but somthing to cover basic operations. 

I'm pretty sure the online only thing is an Anti-cheat measure. I  had an error message come up and anti-cheat was mentioned. The server is too weak to handle the traffic. Things should improve if they can upgrade the server and kill the bugs. 

But I agree. This game needs tooltips or a small manual explaining what does what. It could just cover the shop items and main screen buttons and that would help a lot.
