Using GDevelop, you can create any 2D game? Can you make a game like agar.io? Can you make objects dissapear from the screen, and objects come to the screen?
You can create object at runtime (instances of the objects created in the object editor) and destruct them at runtime.
If you want to create an agar.io like game, the network part will be complicated.
Is it easy to create a game like agar.io if there is no network part.
