Hi DonPuno! wolf here. I thought the idea of the game is very cool! To be honest, this is quite impressive for your first Unity game, nice job! I like the changing terrain types and the towers which damage you. Although the ball was difficult to control, I got used to it. Also, the music was really nice!
Now, idk if the cube bullets are supposed to hurt you more, but they didn't seem to have much of an effect. Also, having a restart button that can take you back to a checkpoint would be really useful. I got stuck in the potholes area with a score of 6507. Having a different text font would be nice as well, but that is up to personal choice. All in all, cool game!
