A good old DOS maze game - 3 episodes (former Shareware)
Find your way through the dungeon, shoot all kind of monsters and collect 4 keys to unlock other rooms. There are many special things as teleports, hidden passages, rolling balls, guntowers, doorswitches, lava, bulldozers (to remove walls, lava, etc..), heal potions, and so on. Also you can swim through the rooms.
Don't forget to save your game often to prevent you from being forced to start over from scratch if Sir Merdimick dies or gets trapped.
A hint: You can hide from monsters by standing in corners ;)
The game ends with a big boss. Good Luck!!

This is a DOS game, so if this game doesn't run on your computer, try to use DosBox ;)
