In Crush The Tower, become the best knight in the universe and save your princess that is locked away on top a tower. Maneuver and ascend the tower as fast as possible to rescue your princess. Collect coins and use it to upgrade your armor and purchase power-ups. You must keep clicking if the red bar reaches zero you lose.
Time is limited (see bar at the top), so keep chopping as fast as you can, each hit will give you additional time. Collect golden coins to buy upgrades in the summary upgrade menu. Get combo bonuses when you are tapping fast enough and do not hit obstacles (combo bonus = coin value multiplier).
At each 100 tower blocks you chop away, a princess is held that you have to save. The tower will get harder and more dangerous after each princess. The first 3 princesses will unlock a special potion, that should make thing easier for you to crush the castle. When unlocked the potions will appear randomly in the gameplay.
There are many Quests (achievements) that are worth extra money when unlocked. Each time there are 3 active quests you can complete to get free extra coins, check them at the top of the summary menu.
