Character designs, visuals, graphics are all amazing, though the quality was not the best because of my device, I say it will have better quality depending on the device. Gameplay is smooth, storyline is straight forward, music is ok (I have listened better), and pretty F2P friendly, which are rare. I do play this as a side game that I don't focus to and it's pretty smooth and not that really repetitive. Overall great game for any tower defense game enthusiasts out there. But do use your characters to the full potential to make it kinda F2P friendly.

Graphics, music and storyline are good enough to satisfy , gameplay can be a bit laggy for me but otherwise it's good. The only thing is the rewards. Not quite generous like HRS and HI3. I think a lot of players agree that the anniversary rewards were quite disappointing. And how smooth your gameplay is really depends on the device (in my experience at least). Out of all solid game. (nah not really :3)
