Don't ask why the title guy is a Harry Potter look-alike. He's actually called Hans Pötterman; not Harry Potter. He's also from Germany, not the United Kingdom, and he flies on a magic sickle. Use A and D to go back-and-forth, and the W key to jump. Avoid falling and non-falling objects as the come your way.
All the code is by SouOVictor, with some minor things being done by me: adding some new boats/ships, and fixed the grammar. (Sorry, I just dislike things that are misspelled) Thanks for reading if you did. P.S. Hans Pötterman blesses you dearly.
