I bought this game on Steam and played it for a bit. Here are my thoughts: Firstly, I bought it because of the GTS theme, but the two-ball gameplay is really unacceptable to me. GTS games are meant to be relaxing and allow players to experience the growth theme, but controlling two balls is just too difficult. However, controlling only one ball results in less damage; the game mechanics are very poorly designed. Overall, I'm quite disappointed. I hope the developer sees my feedback and will consider incorporating my suggestions.
