Has anyone tried exploiting the game?

[McNoobster]

It is technically impossible to fix game stealing, because to play another user's game, your computer has to download it first--and the only reasonable way to send it is the same way that .buildism files are formatted.

Once multiplayer comes out, you will be able to make multiplayer-only games, which will be much harder to steal unless you figure out how to edit the code of the actual game rather than messing with the communication between Buildism and the website.

Isn't this the exact reason what they have servers for .-.
