Building a simple level design tool for early layout planning

I've been working on a level design tool that helps with the early part of planning game spaces. It's still in progress, but the goal is to make it easy to sketch rooms, paths, and ideas before touching an engine.

Right now you can block out areas, draw over them, map routes, and play with different layouts. I'm trying to keep it lightweight so you can focus on flow and structure without getting stuck in technical setup.

It's not perfect yet and a few things are rough, but I'm improving it every day. If you build games or enjoy level design, I'd love to hear what feels confusing or what you think should be added next.
