Ok game, but pretty rough around the edges. The instructions on the start screen look like a ransom note, and I don't know why you're linking to a youtube channel with no videos.
Background music is always a nice touch, but I feel that this music was darker than necessary. The concept of "turning on frequency to see the level" is a common approach to the theme for this jams.
Lots of levels though and I enjoyed those I played, so great job!
