Speed Ball

In this game, a ball moves forward and the player must avoid obstacles. By pressing the space bar on the keyboard, the ball rises on three different levels. After three seconds, it falls back to the first level. During a collision with box of the same color as the ball, the latter becomes invincible for three seconds. If the box is a different color, the game continues. In any case, when the ball hits  a box, it changes color and its speed increases. The player can also get points if the ball collides with a bonus box. Only one goal: to have the highest score ! An original "runner" type game
