Apparently there is this trend going on in this video game called Geometry Dash (a rhythm-based 2d platformer) which involves using Maplestory themes in user-created levels. Looks pretty awesome btw
There are more Maplestory-themed user creations such as a Lucid bossfight, Road of Vanishing theme, and even a Hortail bossfight (and more), but those two are my favorites. These levels have received hundreds of thousands of downloads and are even featured by the creator of the game himself giving the series a bigger name in the community. Let me know if you guys play Geometry Dash or what you think about these creations or if there are other games that include Maplestory themes
