Great low code/no code game engine which has been rapidly advancing in feature-set to match more established heavyweights and getting ahead of them in some regards over past couple years. In the past it was clearly overshadowed by alternatives, especially Construct which it built similar event sheet systems to, but nowadays it has many features that Construct is ironically playing catchup to such as their cloud services, 3D support, multiplayer ease of use, editor platform support etc. GDevelop also shares great educational content on their youtube channel and socials and truly is invested in helping new folks get into the scene, as a veteran gamedev who still gets lots of enjoyment out of the tool it's impossible not to notice their good vibes.
