Hello People! Today I made buildit where you build your own generic maps that could (probably will) be in fdphysics! Run the file, and you will get a level editor, and once you are done, send me a screen shot so I can put it in the game :). You will be credited in the credits. 

Controls

Space - to toggle between items
Left click - to place item
Right click - to delete item
F - to toggle snap into place
A - to save a screenshot (Located in C:\Users*your user*\AppData\Local\buildit)
You can make as many maps as you want :)
