I'm sorry about the explanations, I didn't have time to make them and the game clearly lacks them. The combat system actually needs skill even if it doesn't look like it does, because you can play press space again to change the aggro, the enemy robots are a little bit slower than yours. I think you missed a core mechanic (my fault I lacked time, it should be explained), when you kill every robots around an outpost, you claim it and it sends you robots. The game has an ending, please consider playing it again knowing everything that I just told you, I'm pretty sure you can enjoy the game
