Hollow Travel

In this game, you play as a small bat lost in the forest. You eyesight is limited and all you have at your disposal is your echolocation ability to find your way through the forest. If your energy is running out, seek the butterflies to replenish yourself. You can play with a keyboard or a gamepad to control the bat movement, but you can also use your microphone to send waves through the forest and localize any obstacles.
