It's a real pity that the beginning of the game is so well hidden. I tried to solve the sound puzzle, but I just couldn't understand what the radio was saying. It's a shame, because I really wanted to see the rest of the game.
The countdown timer also made me even more nervous, which made it harder for me to figure things out. I hope to see a future update with a few more hints so I can explore the game further!
Good luck with the project!
