Awesome music in this game!

Notes: 1- or 2-player game
Screen Shots

If for no other reason, get Thunder Castle just to listen to the music and sound effects. That alone is reason enough to spill a small pile of cash for this game. It's awesome! And the splash screens for the different kinds of meanies are really cool, too. In phase one, you slay a mighty dragon, which is nicely rendered. After graduating through the green, yellow, and red dragons, you move to the staff-wielding wizards, which come after you two at a time. This is followed by them beady-eyed, pitchfork totin' demons, three at a time.. This is a tough game, since the maze is continually changing, and there are different mazes on top of that. The main reason I set the replay value at 4 was ... the music! It is simply awesome! Best Score: 11300
