I still like it but but your game has two annoying features
The space bar, when typing fuzzy logic, the space bar shouldn't be required. I didn't notice so all I saw was logic.
You can't switch targets. I hit the letter "h" and the computer picked a ufo with long name, I couldn't seem to switch UFOs
This game is great, although it needs difficulty levels as it is, it is too difficult for grade 1-4 kids.
