A bit of info
I created LittleKt due to the lack of a flexible 2D game framework in the Kotlin space. It is heavily inspired by LibGDX and KorGE. If LibGDX offered a way to create games in Kotlin for the web then this framework probably wouldn't exist.
LittleKt is actively maintained with new features being added regularly.
Where to find it
LittleKt is open source and the source can be found on GitHub.
For a deeper dive into why I created it check out the blog post I wrote about it when I first started it.
