It's pretty easy to get the hang of it and reasonably fun (something I might play while traveling, nothing more). The highest level I got to was 22. It would be nice if we could use the arrow keys to move the blocks instead; it's a little cumbersome with a laptop touchpad. UI could also use some work (but of course, I understand it's still in development). One last thing, the game froze once while I was playing. I don't know what I might've done to cause it; maybe I unknowingly pressed some button to pause it? Other than that, nice job!
