I did level 110+ in classic mode (the game over screen doesn't show the level, so I don't know exactly): Score
Great game, I like the music and the art, and how the Tribbles logic works after you destroy some color. And thank you for allowing us to destroy colors while they are grouping, it helps a lot when it gets fast
I think the level 10 could be the level 20 speed, because it takes a long time to get there and maybe a super very fast speed at lvl 50+ (just for no infinite progression).
