Simple, but it works.

Does exactly what it says in a no-frills fashion. However, why cant you choose which level to restart on? If youre working on fine tuning your ear why must you go through all the levels again. Waste of time, surely? Very frustrating.

Would also be nice to change the sample to something a bit more like an actual instrument, though.
