Well done! The game is simple and simplicity is nice. I must say that the game is addicting. The music is nice as well. The only thing that I don't really like is... the graphics. They aren't very good. But I understand that this is a submission to 1-BIT JAM as well, so I understand it. Good job, overall!
By the way, my best score was 48. (Written after 15 minutes of gameplay.)
