Hi Classicwook, thanks for the feedback! I did code in the option to use the direction arrows on the keyboard instead of the mouse, but for some reason it doesn't work on itch. It does work on my site though. http://darkwalllke.com/Games/SimpleRPG/ Please try it and let me know if you prefer those controls.
Regarding the artwork - it's CC0 if you want to use it. (I didn't make it) https://opengameart.org/content/zelda-like-tilesets-and-sprites
