Hey Marco, please read this. The "Light's Down" sounds the in the game is playing the wrong audio files.
"q1_to_q5_lights_down" plays for questions 1-5 (game levels 0-4), "q1_to_q5_lights_down".
"lights_down_classic" plays for questions 6-11 (game levels 5-10),.
Turns out that both audio files are the exact same (besides length) with different names.
Then "lights_down_2" plays for questions 12-15 (game levels 11-14).
In the SOUNDS folder, "lights_down_" 1, 3, 4, and 5 exist, but aren't being used by the game.
"lighs_down_classic" is supposed to play for questions 1-5,
"lights_down_" 1-5 are supposed to play on questions 6-10, and then again for questions 11-15.
Hopefully you'll have this fixed in a future update.
Love the game!
