Very cool idea! The execution of the idea is really polished and the visuals are GREAT! It took me a few tries to almost beat 1/5 after 0/5. I felt like I was understanding the need to stop the revolutions often to buy new planets and place them accordingly (that part is really neat with the ideal temperatures). But balancing/progression currently seems harsh. The jump from 25 sun energy from 0/5 to 250 in 1/5 seems too much. I think 100 sun energy for 1/5 would've been a more fair climb as players are still learning the game. This game has a big potential, especially for "number go up" fans, which I am one myself. Would love to see this game built further! Really GREAT teamwork here!
