Thanks a lot for playing and for the feedback! I'm really glad you enjoyed the resource management aspect and that it gave you RTS vibes. There actually is an end goal. The slider at the bottom of the screen represents the asteroid's position. If it reaches the minimum value, you lose. If you push it all the way to the maximum by launching enough tires, you win. I realize now that I should have explained this much more clearly in the game. Thanks for pointing it out!
