It's not a bad game. But it pretty quickly devolves into a Pay to Win game unless you want to REALLY grind. Even watching ads don't do much as the rewards for doing so are virtually nothing compared to what you need to upgrade. It's a shame the developers are that greedy. They could have made more ad revenue if they weren't trying to force people to pay money, which most people won't do. Especially not with a game that can get pretty annoying when you are trying to invoke the lightning anywhere near a tower, and it instead selects that tower. Can't tell you how many hard levels I lose due to one enemy slipping by when I couldn't kill it with lightning fast enough due to this. This will also happen with positioning your heroes, or using your heroes active ability. And since you are likely to have them near towers, it happens a lot.

The one thing this needs is a "no ads" option for $1.99. If it had that I'd give it 5 stars. Update: Three years later and they still haven't added a "remove ads," very disappointing.

本来是不错玩 但是玩到第15关卡过后 怪物越来越强 还有首次通关金币才2000左右 重复打已经通关的关卡 一场只能获得500金币左右 要升级任何一个东西最少要2000金币 是要玩家怎么升级？？？再说 要人家重复打一个关卡 至少金币也要1500以上吧 塔要升级到3级就需要15000金币 不知道这游戏的制作人是怎么想的 不过游戏玩法是不错 如果金币能容易获取些 或者把 升级所需要花费的金币调低至少一半 不然升级一个东西随随便便就2000 要重复打一个关卡4次左右才有2000金币 一场还要花大概3～5分钟 叫人家怎么玩

画面还行，防御塔范围太小，英雄攻击方式太傻，防御塔研究，英雄升级等太坑，金币必须氪金

太难了，总体还是可以的。
