Hi there!
Firstly thanks for your interest.
Unfortunately yes it does seem, from your description, that the game falls just outside of what ParserComp itself classes as an eligible game. I know when I wrote te the rules that I had to be clear and have a definition in mind. So ParserComp itself defines an eligible parser game as:
"To be eligible for participation in ParserComp your game must have text input, a text parser system and text output as the primary mechanism of control."
Now, if the game allows free-text entry as well alongside the numbered options ("get ball and put ball in box" for example) then I would be happy to stretch the rule; but if its purely number selection then I'm afraid not.
Hope that helps and sorry to be the bearer of bad news.
