Build it, Play it, Print it. Imaginary Spaces is a sandbox game: design a building using touch or a 1-button mouse, play inside the building and finish decorating it, then send it off to be 3d printed. Windows and Mac versions are free online (but feel free to leave some change in the tip jar). We're working on getting an iOS version up on the Apple Store. If you want access to a preview version on iOS, email us info@imaginary-spaces.com Imaginary Spaces is very early in its development. We hope to add a lot of features in the upcoming months and years. For example: multi-story buildings in a single save file, multiplayer, and a lot more fun, interactive elements. One thing our fellow Unity devs might enjoy is that we are exporting STL files. That means you can build in our application, export to STL, apply UVs and textures in Blender/Max/whatever, and import that building into your Unity game. In other words, you've got yourself a free building designer. http://imaginary-spaces.com
