Post-jam, it's the return of Space Crates.  With actual game play -- kind of.  Lots of bugs still, but I think the potential is there for... something.

For anyone wondering how you get nice face-weighted normals (FWN) on your corners:

1. On Reddit, read about how the pros use FWN - https://www.reddit.com/r/starcitizen/comments/3ogi3o/im_an_tech_artist_in_the_in...
2. Look at my Youtube video showing (a) a plain cube, (b) a cube with beveled edges, (c) that cube imported to Unity with the FWN script mentioned in Step 4 - 
3.  Beveled the edges of a plain cube in Blender -- see video above for example of bevel thickness
4. Go here and get the Unity scripts to automatically face-weight the edge normals when you imported the Blender cube- https://gist.github.com/runevision/6fd7cc8d841245a53df5d09ccf6b47ff
   You'll want to set up an Asset folder for the purpose and edit the script to only apply the FWN to models dropped into that folder
5. Alternately, if you want to apply the FWN inside Blender instead of using the Unity script, there's a plug-in here - grab v1.2 - https://blenderartists.org/t/addon-weighted-normals-calculator/643637

Playing with some pre-tethered crates.

Update 6 July 18:  Original submission included a late-breaking bug that killed the emissive lights on the crates, making them look sad.  This version restores the lights.  I rewrote texture management to properly share prefab textures, so now you can generate a zillion crates with no performance loss.  Still no actual tethering feature added yet.

Way too many controls to remember, you should list them on the page.

Textures look awesome, hard to imagine they are just stock cubes like you said. Love the way the grab and drag mechanic works too!

Improvements 

- Box collisions with player

- Space gravity

- Game lags when spawning boxes

- Program a quit function

- There was a mention of a slow mo mechanic but couldnt figure it out

- Also couldn't figure out how to tether boxes together.

Could do some interesting things with this prototype from here!

You did a great job with the texturing especially with the light reflection showing the fine detail.
