Something thrown together in a day. Has an endless world, procedurally generated. You need to run to the pyramid, pointed at by your trusted arrow before your battery runs out. There are creatures out there looking to eat up your power and there are angles shining light with which you can recharge your pack. You could make a run for it, or you could try and think around it.

WASD - MOVEMENT, SPACE - JUMP, LEFT CLICK - FIRE, RIGHT CLICK - TORCH (?!)

Try and stay out of the water :)
