I hereby inform you that your cat (Mr Spiggles) has been stolen.
Please refrain from any attempts at trying to pursue me to get him back. I live in the Impenetrable flying fortress, and it was getting a little lonely here.
Best regards,
Allmight ruler of the Flying Fortress

OK, after receiving this note things have become abundantly clear to you - ur cat has been kidnapped and is now locked up in a flying fortress.
There is only one thing to do - explore, fight monsters and collect clues about your cat's whereabouts to finally face the evil kidnapper.
You can restore your health and save the game's progress at towns. Yep, it's a classic Adventure-RPG game!
Good luck finding Mr Spiggles. Who knows wot horrors he is enduring at the hands of the evil ruler.
