Piano Tone in April's Room

I already got the phone number and the tone. But I cant really differentiate the tone. Can anyone tell me exactly which piano key to hit. They all sound the same 2 me.

Are there only 6 levels? Your game should explain what the score and time is 4.

BTW, is it possible to skip the intro like using the escape key?

Even though the picture aint very good, good work for the effort. If I do this for FYP, I wonder how many lines odf code I must do.

Hit the piano key in this sequence 28561743. This sequence is also shown when you dial in the correct number in the phone. Note that there are 9 keys in total, the last key is not working. Count from the left.

Yes, there are 6 levels, each with different gameplay.

The score is for you to challenge the leader board, submit your score
While the time is to indicate how much time you used which is useful since you can only use the first hint after 5 minutes.

Yes you can.
