Doodle Kingdom 

Doodle Kingdom is an exciting brain teaser game developed by JoyBits where your objective is to combine elements and create new creatures and others. This puzzle game is suitable for users of all ages, offers detailed instructions, and provides you with various power-ups.

You can choose between three game modes (Genesis, Quests, and My Hero), acquire power-ups directly from the app's interface, and read the gameplay instructions whenever you like. What's more, the game is available in many languages, allows you to disable sound effects and background music if necessary, and uses a small amount of CPU resources.

Even though I never played this type of game before, it wasn't difficult to comprehend the game rules and complete challenges. You can create new creatures or elements by combining various components (human with life, magicians with water, etc.) and increase your overall score.

Besides offering you a fun and addictive gameplay, this app also provides you with detailed information regarding the elements or creatures you create. For instance, it shows details about earthquakes, magicians, etc.

All in all, Doodle Kingdom is an entertaining puzzle game that can keep you in front of your Mac for hours. Plus, it comes with a very reasonable price.
