Echolocation

A game where the protagonist uses soundwaves to find his bearings. In a forest, our bat and his two older siblings are feeding on a fruit tree, until a snake that lives in it attacks them. Confused and scared, they fly away, but the younger bat crashes into a tree and passes out. He later wakes up by himself, frightened in the complete darkness, and must find his way back home using nothing but his echolocation to dodge obstacles and enemies.
