This was one of the first pieces I learnt when I started studying piano a bit more seriously. For me it was a great school, because it is easy to play, but difficult to master. I suggest you to search the piece played by Brailowsky. In the score that I studied, there is a "stretto" during the last "forte". You can hear it in the Brailowsky record. It adds much to the execution, IMHO.
