Game Description:Boktai puts the power of the sun literally in your hand, in this innovative new action adventure from the mind of Hideo Kojima that incorporates actual sunlight into gameplay. As Django, the boy vampire hunter, you must venture through bloodcurdling dungeons to purge evil demons from the world. Of course, your powers are stronger by day, and using a cartridge built-in solar sensor, the amount of direct sunlight when you play the game will affect Django's powers and weapons, the strength of your enemies and your ability to destroy them. Some bosses can only be killed by exposing them to real sunlight, so make sure you have plenty of sunscreen! Note: Angle your GBA console away from direct sunlight to prevent your Game Boy screen from degrading.
