I am well experienced in both Unity and Gamemaker Studio 2, but i have also started using Godot and Unreal Engine recently.
I use Aseprite for drawing pixel art, Blender for 3D modelling and Photoshop and Substance Painter to make textures for my 3D projects.
I am very well experienced in C# and GML, but i have also worked with C++ and Python previously.
Recently i have started learning shader programming with HLSL as well.
