Hi, I am working on a little Python game these days called PixelTerrain. It is not available to public, but I’ll upload a HTML Demo version of the original code later this week. Here’s the wiki: www.pixelterrain.fandom.com
P.S. I need more time, too many bugs.
Edit(10/23): Sorry, can’t get the code to work on Mushroom, but I got it to work here.
