Reviews
總遊玩時間 約90分鐘 評價無中間選項,故好評鼓勵自製遊戲 --- 以台北滅鼠為己任的微倖存者類遊戲 有6大關卡、6隻BOSS老鼠 美術音樂部分可以明顯感覺是AI素材 商店購買部份建議追加血量上限 boss攻擊判定常會和預期的不同 尤其是出招傷害範圍顯示 後期有些老鼠可以一次扣大量hp 基本上是靠提升攻擊力和閃避無敵取勝 閃避有時會失靈 武器攻擊範圍的前端(靠近手的部分)判定似乎無效 老鼠貼近時容易打不中 撿取物品的判定建議加大
有些老鼠倒着走 升级只有数值提升 并且收集金币难 升级难度高 可以走到下面UI后面 角色单位被遮挡 简体中文混有繁体中文 机翻中文 容易误触发的删除存档功能 并且没有二次确认 右键的快速移动缺少按键提示 有中文 有成就
Приятная казуалка. Героический крысиный народ бросил против меня в бой все силы и лучших воинов, но не продержался и сорока минут. Всё решает прокачка. 100% ачивок. Отличные саундтреки на Фуд-корте и в главном меню, я бы купил. Особенно на Фуд-корте, это прямо лучшее воспоминание о всей игре. Ну продайте!..
