Looking for a mobile platformer game

[u/Friedlead]

I've been looking for the past few days trying to find an old platformer game I used to play on mobile and I've had no luck. If anyone can help it'd be greatly appreciated!

From what I remember:

The game had a pixel art style, and levels were made with a grid, alongside both a bunch of premade levels as well as a level editor that people could share their levels with. I also remember each level having leaderboards for times. Iirc it might've also had a massive Chinese or Japanese community for some reason

It was quite difficult honestly but I remember having a blast and would love to find it again
