Yeah, I used the wide characters as a workaround to keep the fixed width of the game screen for all three types of fonts. I saw how the help looks but as a lot of content was still missing from the game I decided to keep it as is, and I still couldn't add everything I wanted.
Music was another issue I didn't have time to handle better, so I just added to mute button, and left it as it is.
There is definitely and ending and a nice end screen I spent way more time to create than I should have been. Especially because even I couldn't reach the end during the jam. If you are interested in it and has ways to launch a browser-based game locally, just download it, and change the hero's start position in the /src/world.js file to 10,10,0,0,0,0. But yeah, it's in the red.
Thanks for the feedback! Glad you liked the concept and mechanics!
