Cool concept! I managed to score 7,200 points. That being said, I think there needs to be some sort of progression as it gets repetitive over time. Perhaps even as simple as changing the color of the floor and the blocks.
But aside from that, great game! It's quite challenging, took me some time to get accustomed to the gameplay but once I developed a strategy I was able to proceed without problems.
The graphics are also good. I like the minimalist aesthetic. Overall, good job!
P.S. Please consider giving feedback to our game as well, as we are in need of more ratings. https://itch.io/jam/gmtk-2018/rate/300343
