Thanks for the feedback! well you get more points when you are closer to the center, so while yes spamming will get you a high combo your score wont be a high. I'll implement a highscore feature before the jam ends, I didn't think it would make a difference to the enjoyment but clearly it does!
I was worried if I had to make players hover with the mouse (like in osu) the difficulty would be too high, I prefer for a jam game that players can enjoy the game while not being too stressed about it. But thanks again for the feedback!
