Thank you for your kind comment! The sprites for the enemies, Maus and Grandpa are custom made by our artist Eleonora that I'll credit ASAP on the game page, together with the credits for the background sprites we used.
The suggestion mechanics is mainly inspired by Final Fantasy XII's Gambit system, with some heavy modifications. I'd love to see this text-based game you are referring to, it may be an interesting reference for possible future developments.
Unfortunately we didn't have enough time to implement more levels and a coherent story. I'm glad you had fun anyway!
