Drool Of The Killer is a 3d adventure game with 2d characters where you are BB, who takes an empty bus towards a swimming pool complex. There, you discover a strange world, full of secrets and with a hostile presence. It is now your duty to find a way out as soon as possible.
The game has about 10 minutes of gameplay and can be finished easily in the first game. The focus is on visuals and dialogues, which seem to explain the game's narrative. The gameplay is nothing exceptional. Just walk towards the doors, cross swimming pools and avoid obstacles.
