Congrats on the IGN 10/10
Looking forward for the sequel! Can't wait to see how the cliffhanger concludes.
The concept is very nice, but the trial and error type of gameplay becomes quite annoying after a while. I think to improve this, you could slightly hint in a way where you are supposed to switch channels on a level, like an arrow or a small "puddle of static" on the ground. Another way to fix this would be to show a small preview of the next channel somewhere, or at least to let the user switch back fast if they end up above a death zone.
