Play Ready to Roar online for free

Roar with the ThunderCats, and save the day! For starters, only Lion-O, the main character, will be available for you to play with, and only one location, but earning coins along the way unlocks more characters, each with their own unique abilities, as well as various new locations to play in. As you advance through the locations, click the sword button or press the spacebar to attack, click the arrow or press the right key to move forward, having to advance without the lava catch up to you. Attack the fireballs and other things that will come towards you and are enemies or traps, because you lose if they hit you too many times, while also collecting as many coins along the course as possible.
