    Pixel Rush

    Pixel Rush

    Avoid enemies that want to kill you.

    Avoid enemies that want to catch and kill you. Buy more lives, faster speed or regenerate your lives in the shop. Change the background of the game, the color of the player or another language! We have several types of enemies: Red ( BasicEnemy ), Gray ( HardEnemy ), Green ( SmartEnemy ) and Blue ( FastEnemy ). More enemies will be added in future updates. The red enemy is basic. Gray is more of a special one that only occurs on hard and changes its speed whenever it touches the side of the game window. Green is found in all levels and chases the player so that he cannot hide in a corner. The blue enemy is the same as the red enemy, only faster and takes more damage. First beta for new 1.2 update is now out! Try it out!
