提点建议。 Provide some suggestions

The gameplay is a bit monotonous. In the later stages, there is a lot of money and I keep buying Guardians, but I cannot attack them. My skills are a bit lacking. After 20 minutes of leveling up, I have nowhere to spend my money. I suggest adding more skills, such as a catapult that can be purchased but is limited to purchases。
游戏玩法有点单一，后期钱多一直买卫士无法攻进去，技能有点少20分钟升满后钱没地方花，建议多出点技能，比如投石车可购买且限购
