Very interesting experimental gameplay. I liked the shader, I like the sound design, the story was very short. I would like to see what else you could do with the boxes.
As with the interaction itself I wasn’t quite sure what I was experiencing and why I was experiencing it.
The best part about this was the sound design. You really could feel the overwhelming panic towards the end when the volume of the sine wave increased dramatically. Would love to see what else is in store! Nice work
