Only people that contributed to the Indiegogo campaign were from GG community. Yesterday itself I'd released full block library for GG. As the campaign is almost ended..or I say it is living on fume for few more hours ...Since, I haven't received any support from other communities hence am not obliged to add support for there game engine... I'm not keen on S2 now...as the developer has already abandoned the product and CC6 is not financially viable...
Currently testing AppGameKit...
Godot and Unity C# is next in line...
Sorry to disappoint you..Hope you'll understand my state...However, the final steam version will include my own 3d drag and drop game engine...way better than buildbox 3... check back later if it interest you...
