The free version of the game won't use doodads embedded inside a level.

It could be possible to make exceptions, and allow free DLC or special promotions which need custom doodads attached:

Add a Signature property to the Level data (str)
It would be a signed hash of the remaining level data sans the key.

When the game is loading a level which has a signature attached, and especially for the free version, the algorithm is:

Take the Signature value from the level
Serialize the file attachments data and hash it.
Verify the signature matches the hash

Or something along those lines. If the signature is good, the level is allowed to contain custom doodads and be played and edited. If the hash is over just the attached files data, it allows free users to edit and remix the level and use its embedded doodads to their heart's content, but if they break the signature the free game will no longer be happy.

The doodle-admin tool can have the feature to create signed levels and levelpacks.

Implemented in 82884c79ae.

Levels and Levelpacks can both be signed and the free game will load their embedded doodads even for the free mode.
