Great demo, interesting concept. I felt that the buttons (when on Android at least) are back to front to my expectation. I feel like left should rotate the top of the central core to the left, and it did the opposite. Very interested to see where you end up with this, lots of options for dynamic objects coming in, powerups, shields etc. Nice work!
Thanks for playing the game and your feedback! You can change the rotation direction in the options screen. You can access the options by clicking the button in the main menu, or the pause button in the top right of the game screen. Then for the direction you can change it "Right turns clockwise". Hope that helps. Please let me know if it does not work.
