Great game. Reached 11K points.
I sensed a Tetris vibe form these, and although I'm not a Tetris fan, I found it quite entertaining.
The colors were kind of soothing, but not boring.
The music was right on point. Couldn't think of a better choice.
My only observation is that it would have felt better in the end to have some kind of highscore.
--EDIT--
Replayed this game today (2021), and it is still fun. Managed to get 45K points and the "TERRIFIC" audio. Nice game =)
