Courage

Courage is a 2-4 player battle royal style conquering game. You are a want-to-be hero and have awoken on the island of courage, a place to prove yourself but seems like your not the only one. You and you're friends build the island and use its various unique movement mechanics to approach and attack each others castles, use the moving terrain and items to get there quickly and effectively. once you take an opponents castle they work for you, meaning this game starts as a competitive game but ends co-operative.
Last castle standing, wins!
