Thank you both.
@ddabrahim:
You don’t seem very positive, it is a bit puzzling why are you still here if you are not using the software and you see the future uncertain. I value the information you shared but I hope others also going to answer my questions unless they agree in which case I’m not very motivated after reading your reply. AppGameKit is not something I’m interested in, I prefer something require no code and comes with an editor but what you told about HTML5 make me consider to find something that can export to Android and Windows natively in which case I left only with Clickteam. But thank you for the suggestion.
@Matt.B:
The isometric movement looks nice but there is a lot more to it than just movement on a small land. There is also combat, weapons, items, progression, shop, mobs, crafting may even building and a huge map. Unfortunately I don’t see people using GDevelop for such complex games and what ddabrahim told about the loading time because of the images also leave me with the question if GDevelop can support a complex and big game at all. But thank you anyway.
