Would a WebGL version play smoothly enough to justify posting one? You'd get more ratings. Mine didn't run too well with WebGL-- framerate dropped quite a bit. But I posted it anyway because some people refuse to download builds.

I should have been shift-running the whole time. I'd like to be able to move my camera a little higher and the clicking to grab the boxes is for some reason not responsive (maybe use raycast instead of OnMouseDown or something?). Also I'd love a key to simply let go of the box instead of being forced to throw it forward to get rid of it. For the short amount of time you spent on it, it's very close to a solid foundation to something that could be truly fun. Once the core gameloop is fun and feels right, throwing in a few quirks and twists and personality would be quite fun indeed. I have an affinity for games that revolve around boxes. I made one myself for a previous Ludum Dare called United Parcel Force. Check that out, if you desire. https://ldjam.com/events/ludum-dare/40/united-parcel-force

It's a fun game, but I had a few issues. The biggest one for me is no way to exit without task managing out. And the main menu for me looked strange, did you use a plane and not UI? The clicking mechanic was ok, but if I was too close it would often fail to register
