Not bad for a first game !
I did a Pong clone too, you can check it on my profile, I even shared the code...
You could try and make the AI a little bit more forgiving :)
Very strange game... Half-baked for sure, you never seems to loose, but I really like the crude graphics and he fact that you kill the enemies with words.
Keep up and you'll end up doing some real thing :)
No explication whatsoever on why you're right or wrong, no end to this "game", and really crude graphics...
You should add an incentive to solve the puzzles and maybe refine your graphics and interface...
