Controls: W (walking)- moves the character towards the mouse, while making some noise. Space (clapping)- makes lots of noise for the express purpose of detecting your surroundings. S (sneaking)- moves the character towards the mouse slowly, but makes little noise. Good for getting past enemies that are too close to walk by. 1(decoy speaker)- puts down a speaker that relays the sound you make to its location. Make sure you're far away from enemies before you start making noise with it.
The premise of this game is that you can only detect your surroundings with echolocation. If you take lots of footsteps, or clap, you can detect the goal and your enemies--and they can detect you. This is more of a concept game than something Like Trump Card.
