Lemme use this opportunity for having your attention to suggest some form of collaboration or even a merger with the Godot game engine:
• itch.io users could launch the Godot Web Editor to quickly make prototypes or simple games right on itch
• Publish from the native Godot editor directly to itch.io
• Godot adopts itch.io as the official asset store for art packs etc.
• Introduce social features for devs and artists to collaborate with each other:
• A publisher could choose to add a “Fork” or similar button on their itch.io game page that downloads and opens the project source in Godot. • All "forks" published that way would include a link to the original game's page, and so on.
I think Godot+itch could/should become the Github of Games :)
