Mad fingers

There was a small town inhabited by fingers. And they lived a calm and happy life, but everything changed when a fat psycho decided that happiness is a mental disorder and he should cure it, so he built a hospital and captured lots of happy fingers willing to relieve their horrible disease. A lot of them died during his experiment, but he never cared about that.
Now it is your turn to help those little fingers to undergo fat finger's treatment and stay alive. It is your destiny to SAVE THEM ALL
