The game has good visual, but gameplay is boring. The difficulty is really easy, which is not wrong, but I think being a bit harder is important for rhythm games. Also i don't think changing the cows position counts as controlling the gravity... I don't only want to criticize tho. As I said, the game has nice visual and i am sure you put a lot of your time into this game. The limitation was really hard to include in a game.
Nah, you don't have to hold back I absolutely agree. I am not the greatest at coming up with good ideas for games. I was also disappointed with how boring the game became. I am happy that I created it though as it was my first game and I learned a lot, mainly that everything I do will create a bug that will take me an hour to fix :). Thank you for the criticism.
