One of my suggestions is new building blocks. I’m talking about walls. It would be great to have walls with 2 inside faces and walls with 2 outside faces so whenever you want to create a room inside your base (for instance) you can put the inside wall.
My second suggestion is being able to change your haircut in game and to dye it (even making a degraded!).
The last suggestion is changing a bit the colors we’ve got to dye armours with because the lighter ones look like grey in some armours (light purple, for example).
