Special thanks to DinoDev for being awesome.
If you've ever wanted to make something like Mario Maker or even a 2D Minecraft, hopefully this will help!
NOTE: I could use the same object if I wanted, however the "Position" and "Destroyer" behaviors prevent collisions from merging, which I don't want to happen for performance reasons.
Click to select object.
Press "Space" to place the object
Press "Backspace" to remove placed objects.
