I would like to share this work that I'm doing on top of Super Mango asset pack: https://jonathanperis.github.io/super-mango-editor/
It started as a simple sandbox gaming to learning purposes, written in pure C using SDL, and then later on we evolved to be a full editor so you can build phases just using .toml files and the engine will take care for you and parse to a running phase
This editor have all the sprites that Juho designed, with some additions of color variants so we can elaborate another biomes as well

There you can learn all the content about this experimental engine build on top of the Super Mango assets.
Thank you Juho! I leaved credits for you on the website's footer about the game sprite.
