Hi Mastro2k, thank you for your thoughts and feedback about this game! I totally agree with the audio. Just a couple of sounds can have such a big impact on the feeling of a game. I like your ideas. Switching the background is a cool thing. If I bring that idea further, then you could also create a lighting show (like in the disco) for each level that would be in harmony with the song. Thank you for your time and good luck with your game!
