Couldn’t finish the game -_-
I learned using unity 3d and making a 3d model in blender. Had this idea to add ourselves into the game. That became a success tho it’s currently still buggy.
Check out my first 3d model: (somehow it’s buggy tho, that some of the parts just become transparant in game)

Opening the “Mesh” menu at the bottom and opening the normals section of that.
Then click recalculate outside.
