I will tell you how to complete the puzzles in the game. Firstly you should click on the radio and then listen to the notes being played. You can then play these notes on the piano. You have to be very specific about where you line up where you are clicking on the piano and if you accidentally play a note twice or play a wrong note you will have to start again. On the wall in the sitting room is a picture of the C major scale, you should play this scale. It also has a picture of which notes are which on a piano. Next you can go to the bathroom where it is dark. Press space to use your torch. If you stand on the toilet and look at the wall you should see a sign with soom notes on. Play these notes on the piano. It does not matter which octave (a group of eight notes) you play the notes on the piano but it is best to play them on middle three octaves as some octaves are not correct on the ends of the piano. Annoyingly there is an error where the house is unlocked at the start of the game.
Please rate my game and give feedback as I think I might have fewer ratings than others.
