Another experimental game mechanic I’ve demo’d a few times is following around a sound using directional audio, check out the full post to give it a go:
This is more of a proof of concept than an actual game, but it’s entertaining for at least 30 seconds.
Player one (blue bar) uses A and S keys to move left and right.
player two (red bar) needs to put on stereo headphones, close their eyes and controls their player with the left and right arrow keys.
The idea is that player two can’t see where player one is, but that can hear the sound that they give off and try and chase them around, while player one tries to stay away.
