This is an unfinished game based on the Grimlor engine — a trip inside your computer to hunt down viruses and save your system. The reviewer at ClassicDOSGames.com really liked this game. The first level is complete and is probably my best effort on level design in a game of this type.
Note: Only one episode was completed — the other two episodes contain unfinished levels. Play the all-new modern Grimlor Web version where this level was made into episode IV!
Speed adjustment: Edit the file named SPEEDAT.SR and change the number to something like 300000. The higher the number, the slower the animation. Consider using DOSBox for more playable speeds on faster computers.
