It can be activated or desactivated using the "Turn Around" key.
Notice also that I made the flashlight 'right-handed' instead of being centered on the player:

Problem: I can only use the flashlight on maps that been designed for (a map containing a SE with lotag of 50).I tried to program it to make it compatible with other maps, but there are a weird bug that project the APLAYER sprite on wall instead of normal light...
