You might also take a look at PICO-8 (https://www.lexaloffle.com/pico-8.php). It's a "fantasy console" also programmable in Lua. It includes code/sprite/music/sfx editor. So a complete environment to build games. And the best thing is that the cartridges are also PNG files (example: https://www.lexaloffle.com/bbs/cposts/2/29524.p8.png)
