This is the main screen. The top button allows you to continue the monstrous campaign, while you can also play PVP and Survival. Overall, a very intuitive interface.
An in-battle screenshot. Controls are easy to learn. You can jump, attack, and use special abilities. Some abilities are good, while others are bland and boring. Most battles are intense and difficult.
PVP is immersive and nice. You can progress up the leagues, beating other players along the way. You can earn gold and XP from playing matches.
This is survival tower. It can be fun, but it's not very creative. You just fight opponents until you die, earning rewards along the way. It gets boring faster than campaign or PVP.
