Think about names that you think would suit well for GDevelop (unless you think GDevelop is already perfect for what it is).
It can be something fun, with a very depth meaning... or not at all, just a name that is fun and sounding good!
A few random ideas to get you started: Cilintilla, Buildtiful, Igamination, Lila, PiliPlay, Damdamo, Orthoverse, Elexlate...
