The deadline was closing in and I got anxious that I'm spending time walking around the home making coffee instead of coding. I ran back to the computer and got back to it but the code was all tangled up, I thought the fatigue must be playing tricks on me. I hastily finished the game and submitted it with satisfaction. I scored 4615 and got good reviews.
Congratulations on the game. The idea is cool. It really tests your multitasking and touch typing skills. One thing though - I see it that the UI says to press space to stop coding, but I barely noticed it. It is displayed only when you are already concentrated on the letters which makes it almost impossible to notice.
