sorry if it sounds stupid but is that possible to save a . exe or something or game engine is only accesible with a full blender instalation.
This’ll create an exe of your game. But it won’t function yet - you still need to grab a dll or 2 from your blender directory. Zlib.dll you’ll need - I forget if it’s the only one though, sorry.
Just drop the dll file(s) into the same directory as the exe file, & you’re good to go.
