Correction, it is Defold, and the source pngs must be referenced to pull them into the game.

Took me a while to respond:
I'm still debating this, but according to my latest license draft the answer would be no: as in its current form the license states that it can't be used in forms that allow for easy extracting and reuse without buying a license. In other words redistributing my stuff without my control. That would include open source games and asset store templates.
I'm still wondering about this since I love open source, game jams, and all the good stuff. On the other hand I also put tons of effort into these packs and want to respect myself and my hard work :) I also want them to be distributed in a certain way, controlled for quality.
I'm preparing that license right now, might take a moment to settle though. Huge shout out to all of you who kept reminding me to finally prepare a proper license.
