The gameplay is almost the same as in Breakout, except that your character has to use a shield in order to bounce rocks back to the walls and break all the blocks at the top of the screen. This makes the enemies that stand on the blocks fall to the ground.
In Knight Kunibert you can find more than 20 different levels. In each of these you have to fight different enemies situated on different platforms. They resist your attacks differently, so you'll encounter some variety in the game.
Knight Kunibert is a traditional and fun arcade game with a setting that's completely different from most games in this genre. The graphics are quite good, too.
