It is quite difficult for me to find words in the levels. I usually can only come up words with 3-4 length… However, I have to admit that I have not seen a typing game for a very long time and this is definitely very fun to play! And being a game with ASCII art it’s even better!
The only thing I hope can be changed is that the sound effect when you have exposed the opponent’s spy or when your spy has infiltrated their HQ. Those sound effects are quite loud and disturbing. They do not fit your theme very well either in my opinion.
However, I liked your game very much!
