I've recently started working on some Beta Floor Builder UI concepts for Baldi's Fun New School Ultimate to help me figure out what I want the design to end up looking like. Here's a look at 2 different concepts I've created below.
This was the first concept that I created of the interface back at the end of September.
This is the second and latest concept that I created earlier today. It includes some additions compared to the earlier concept, along with a mobile UI directional pad concept. This d-pad would help make moving around in the floor builder easier along with rotation arrows which could be pressed to change the direction the camera is facing.
