As opposed to a 2D Game Engine in Kotlin Working with Kotlin? Why?!?
If you want to create games using Kotlin, you can try my 3D Game Engine: minigdx (https://github.com/minigdx/minigdx).
Or other game engine:
- https://littlekt.com/ (LittleKt (Little Kotlin) is a multiplatform 2D game framework written in Kotlin)
- https://korge.org/ (Korge - Modern Multiplatform Game Engine for Kotlin.)
- https://libgdx.com/ (LibGDX, it's for Java but you can use Kotlin, if you don't want to target the web platform)
