The multi-platform GameMaker: Studio engine from YoYo Games has an analogue of the Asset Store for Unity.
The resource store will allow some developers to sell animations, sounds, backgrounds, objects, scripts, shaders, sprites and much more to others. GameMaker: Marketplace is already available to all GameMaker: Studio license holders.
“The YoYo Games team has been working tirelessly on Marketplace for many months now, and the response of our users to the early version exceeded all our expectations. We are very pleased to provide another source of revenue to developers,” said Marketing Director Michael Cassius.
By the way, GameMaker: Studio has recently become increasingly popular among independent developers. There are no mobile hits for him yet, but there are enough resonant projects for Steam. Games such as Gods will be watching, Hotline Miami and Home were created on it.
Hyper Light Drifter is also made on the basis of GameMaker
