Thank you, for your feedback! 

Yes you are right, for now it is not optimized for mobile. But you are right, i should optimize a bit, because a lot of people use just mobile (didnt expect this) 

You have to slide with the mouse over the i, then you see the text for the roar-power. But yeah, for mobile i can make it clickable. It says: "This power indicates how strong a monster can roar. In other words, how fast the projectile flies in the battle arena."

I hope that too Would be awesome!
