Ive been meaning to make this universe into a game for some time now. However I've never been good at coding, or 2d visual art. When I learned Tinkercad is when I learned to show off some concepts. These are concepts for fighter planes on the world of Merith.
If you mean the small triangle near the monter right hand, its beacause of the upper right ledge of the wall, but indeed there are many geometry problems, all the level ita made of blocks and not are well aligned, but due lack of time its the best i can do for now 😨🙃
The overall geometry is a good start, but could need more details using pre-designed instances. Different materials between floor and walls would give a sense of direction. Lights in different colors can create the sense of being a closed or open space using blue and yellow tints.
