Proof of concept for making a 2D game in Core
Make your own pixel art for use in Core!
Download the setup Pyxel Edit starter file that is already configured for this:
https://www.luasnippets.com/wp-content/uploads/2020/09/core-pixel-art-starter-93-53-8.zip
Create your own pixel art inside of Core! Have fun.
* Make a picture frame that resizes with the artwork
* Draw pixels from the bottom-up so they natively align to the ground.
* Check next pixel to grow (width) the current pixel
* Use spacing for "empty" (56) pixels
