IDDQD + IDKFA = MURDER THEM ALL!

I would play this game in class on my laptop! Was so addicting! I managed to play the game to the point i tried to clear each level 100% by hugging each wall and pressing space to look for hidden doors. No corner was missed!

What bothered me about this game was the demo had a completely different set of levels that weren't in the full version! That is the most memorable set of levels i every played. They are archived somewhere.
