Hi again all! It's been a long time since I last posted here, very excited to show my newly-launched, Hammer-inspired, level design tool "Prototype". We've added some fancy new items like Extrusion and Face/Vertex coloring, edge selection, and other nifty bits (if you've been following Prototype's big brother, "ProBuilder"). But mostly, the workflow has been streamlined, simplified, and geared toward building test levels, prototypes (see that?), and even game props/etc. Oh, and it's dirt cheap, so everyone can use it! 
I've pasted the text from the Unity Forum post here, and now I need to go sleep a LONG time, it's been quite a week, big thanks to everyone who can take a look, and pass it on if you like what you see. Looking forward to feedback, comments, and awesome new creations from yall!

We are very, very excited to finally announce "Prototype"!
Prototype enables you to build entire game levels (or objects) with speed and simplicity, then test instantly and tweak immediately- there is zero lag in the creative process. This is the powerful core of ProBuilder, but stripped of specialized functions and focused on speed, available for just $15 for the first few days. Check out the video below for a quick overview, including a demonstration of the new Extrude feature!
Prototype is the core of our powerful mesh-building tool, ProBuilder, stripped for speed and simplicity. Prototype is built specifically for “prototyping” a level- building up the basic structure and flow of your game without wasting a single second, and enabling true speed-of-your-mind game creation. With the ability to build, test, then instantly tweak, test again, etc, your workflow becomes incredibly fast, efficient, and truly fun.

Using Prototype, you can quickly build great looking early-stage structures, props, walls, bunkers, vehicles, virtually anything at all. Test and tweak instantly, then replace with final models once your artists catch up- if they can! Prototype also includes ProBuilder’s ability to quickly colorize faces without adding a single draw call, so you can designateteam areas, or just get creative with colorful dev textures.
Lastly, Prototype includes support for the Detail, Mover, Collider, and Trigger types from ProBuilder, so you can even use Prototype with dynamic doors, lifts, spawns, barriers, player clip, and much more.

Whatever your project, Prototype can accelerate it’s development, ease your stress, and ultimately allow you to ship abetter finished project. Give it a try, you’ll wonder how you ever worked without it!
