Press & Hold Space to use the Flashlight. Its the only thing that can scare off the enemy. If it has 100 Attention, game over. Your battery power is limited, but will charge if you're not using it. Hold Z to go into supercharge mode. However, this will remove the light from the room completely and will double the enemy's speed if they're there. The goal is to survive for a total of 200 Seconds. The enemy appears more frequently the longer you go.
I recommend getting a countdown for this game. Note: After 100 seconds, The enemy will get relentless and thus, will double their speed in both situations. It is never a good idea to supercharge when they are present in the 2nd half.
