Graciebuns, hi. Thank you so much for playing the game. I made it WebGL at the last moment, ran out of time. I used a gamepad to move, sorry the mouse is way too broken. Press B (gamepad or keyboard), you probably have thinking about it, it will toogle the screen to split, you should see the barriers on the top, there is a gap to the right. As for the speakers, I'd like to develop that a little more. Again thank you for having a look.
