I'm a professional developer/programmer/computer scientist (not in the games industry) looking for a little side project. I enjoy 2D top down games like Rimworld, Prison Architect, Faster Than Light, Stardew Valley,  Factorio. I'm located in Stuttgart (Germany).

Do you know Unity/Unreal or other game engine? what your strongest language? C#, java, HTML5 or any other?

I did some little projects in Unity/LÖVE/Godot and can among other languages program in C#, Lua, GDScript. Most often i like to do proof of concepts for example in creating an AI with A*, Moving AI on a Hexagonal field, Generating tilesets with Perlin Noise and so forth.
