This is another Japanese brew by "Hatena mark" his nickname means "Question mark" The game itself is a port of a flash game he made (see it here). This one was released 09/01/07
The aim of the game is to copy the computers notes, 20 misses results in a game over. I don't think you're supposed to press any buttons on the vertical moustaches.
