Welcome to the maze called Grotto. You will find yourself in the atmosphere of the early Doom games. Around every turn or behind the next door another monster or mutant may be waiting for you. You are armed with a crossbow and it is quite enough to hit the enemy. If you act quickly, not letting the monster shoot first. Complete the training level to understand the game mechanics. It's quite simple. Controls are with arrow keys; to double jump, press the up arrow key twice; to shoot, press the space key. You will quickly master all the rules, and then all that remains is to run and shoot at the Grot.
