Hey, nice work !
I know others said these things already but I agree with them so I'll probably repeat things you've already read, sorry ^^
I love the atmosphere of your game, you managed to make me feel like the frog is some kind of zombie crawling after you. The thunder, sfx, lights, choices of texture contribute well to this atmosphere.
The gameplay is nice but 8 minutes is too long, I would have said 2 or 3 minutes because after that time you've had time to understand the gameplay and be stressed by the frog. OR, make it infinite time until you die, and add a score that depends on how fast and how precisely you fix the radio signals so people can make a scoring contest.
