Nice little game. One thing that kept throwing me off was the controls didn't align with what I saw. The correct directions are linked to the correct arrow key, but needing to switch between the up and down keys with the same finger didn't feel natural, and made it a bit difficult. I think 4 consecutive keys would have fixed this (e.g., "ASDF"). Very well could just be an issue for me, though. Regardless, great concept and simple execution, making this a good game over all.
