Hi! The different gameplay from the usual text adventures make this game fresh and interesting; I do believe the claustrophobic, rushing, stressful "Alien" feel you have created here brings potential for it to be used again in future games.
By the way, I can't help but notice you have a (very good) loading screen ready at the top of this page, why not use it in the .tap files ? Just a suggestion. Cheers. :)
