Here is a video of a level I made for fun, "FoxGames01 museum", where I show some pixelarts. Then hypothetically I could share this to some friends using the image the level editor generates. Creating this level was actually super easy, it took me like 7 minutes.
this is how the PNG of this level actually looks like: (then you can import this in the game and it will look exactly as what you've seen. or you can share this image with your friends so they can play your level or whatever do you want)
Size of the level/image: 2.46KB!
If you are interested in my project please follow me in my Twitter @ZorraMacho. Oh, and if you are confused about some aspects of my game you can play the original with levels created by me, it's on my profile.
