This is a really neat game. It needs a mechanic to create a sense of time and decision-making, as right now it's kind of just a sandbox self-refereed game. But the idea of placing your own spawns and dealing with them has great potential!
Hey, I will keep note of this decision-making idea!!! Thanks for the feedback, I created this game concept in GDevelop, which is quite limited to small projects. I am remaking it in Unity Engine to grow a bigger scope. <3
