it seems focused on online games, MAEK ONLINE PLUGIN DAMNIT!
it probably wont contain the same amount of power as construct has, in terms of DX9 stuff, fast engine, ect. i havent seen a gamemaker which comes close to the speed of construct, and i dont think i will for a while.
black crystal is kind of a silly name for a gamemaker, it doesnt even having anything to do with creation.
it looks extremely new so i can't really say anything else about it.
