So it seems I figured that any sort of 'help me create game' wount work by no means. And this is not because ppl dont want to do things but probably got something to do with commitment level. Anyways it seems I can do all I need as per my workflow on my own (HUH!).
Scaling objects for the first level, this is how it looks in blender, It looks the same in Unity and I am pretty happy for now. (left most is the original Black Bole size at the lvl start)
I would also appreciate any kind of comments or ideas or feedback from now on!
