If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
In Click 'em Up! 2, all the little characters are running around like crazy to avoid being clicked on. You must advance through 4 floors of 10 rooms with different themes (misc, tropical, tech, horror), and beat his 5 bosses: a crazy fat, an angry cactus, a robot of colors, an elusive ghost, and a giant stone head. Get some CLOCKS and play extra time! You must hurry and click 'em as fast as you can, because when time runs out the game's over, so don't try this game right after you wake up from a nap.
