Yes, you can sell your games!

The license page is very clear on this: https://defold.com/license/

You can sell anything you want created with or related to Defold, but not package the engine+editor and sell those.

Are you affiliated at all?

Edit: ahh just noticed that you are(from comment history).

Yeah, sorry, product owner here!

You can't rebrand Defold and sell it, your games can be monetized in any way you want no strings attached.
