In Pinky's Adventure you're a creature expoloring through the levels to find a yummy golden carrot.
In Crystal Turrets you place turrets in order to protect the 'Life Crystal' against zombies that aim to destroy it.
Collect as many coins as you can. Avoid the enemies and cannons. Time moves with you, take advantage of that.
Mine your way through the blocks and ores gaining money as a reward. Be careful, that pickaxe won't last.
