非常有趣的小游戏。由于加入了升级机制，这点非常重要，使得游戏变得有奖励性。
Very fun！
Great idea, I really like it. This game has given me a lot of inspiration. I would like to make a suggestion: create multiple AI factions (neutral, hostile, friendly) to increase the strategic depth of the game. And thank you for your attention.
Awesome game;
I have released a new prototype test game, Hollow Arena, and I hope everyone likes it.
