With a bit of autoclicker setup so that I could "move" my cursor a bit faster, and didn't have to think that much I managed to get to level 6. Interesting that instead of matching with the one falling, you should match with another one, messed a bit with my head first. The fact that you didn't lose immediately when you get into the game was nice too.
To bad the fullscreen mode messes the screen up and makes it much harder to play. Would most certanly look better on a phone though.
