Simple but fun and refreshing. Good choice of background colour -> good reflection of me playing the game ( me = dissapointment, get it ? lol).
Just few things that I didn't like: blue (static) text being off the screen, no quit button in menu, blue text spawning on top of my cursor.
Other than these small "flaws" in my eyes, it's well made. I didn't even notice there isn't any sound / background music during the first play, however you might consider adding some.
I can't wait for your upcoming games and to check your other games (if there are any).
