Mini’s Adventure is a game that can be played on a PC and an arcade machine. Therefore, the UI would have to be made to accommodate both mediums.
Early on, I decided it should be as simple as possible so the player doesn’t have to look at the UI elements unless they absolutely need to or they want to.
For the theme of the UI, I wanted it to feel simple but futuristic, with the idea being that the player character MINI is looking at their own screen that is on their robotic body.
