If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
This is a fun quirky game where you have to play around with their ages to get rid of the round nasty blocks! You are given a limit of ages you are allowed to use in each level and you need to give the good guys the correct amount of ages to destroy the bad guys. Seems complicated but really is not! Just get the game started and enjoy the fun!
