Escape

How to play:
Click inside the blue circle whenever a white circle is ontop of it.
It should make the same sound as Ajacci's knocking.
If you are too early, it will make a clashing sound.
Too late and the blue circle disappears before you can complete the sequence (or, in longer sequences, it will count as "too early" for following beats).
The timing doesn't need to be perfect: it seems to work even if the white circle is /close/ to the blue one. If it's inside the blue circle when you click, it will almost certainly work.
This probably makes sense for anyone who played some rhythm game that I presume this is modelled after, but I had to figure it out through experimentation. So many lives lost. :(
To the author: It might help if Sis were to play a round or two of the game for the player before requiring the player to do it.
