Such a fun game! Love the art style! And is quite challenging!
On a side note, how do you get a combo over 4?
Please take a look at my game too, if you get a chance!
Thanks for playing! I liked your puzzle game. To get a combo over 4, try hitting the keys a bit quicker, especially when the screen gets crowded. Another hint: try getting to score>15 for a second level of the game!
