This game was developed during a company game jam. All proprietary packages have been stripped from the code.
In Crazy Granny War your objective is to collect materials to build your base before the time ends. When the attack phase starts, you must destroy the construction of the other crazy granny across the street. Of course, you should throw your powered up cats for that. The winner is the construction with most parts.
Disclaimer: no cats were harmed during the development of this game.
