Cool idea implementation question
firstly, of course, I don’t think that Unreal Engine is a good engine for simulation games; in the form of black hole breaker for such games they use Unity, it’s easier there.
secondly, the black hole sucks in crookedly for the first reason, and perhaps because of static objects, and the game crashes if you reach the maximum mass, it’s funny.
thirdly, the graphics are too serious (it lags a lot; it’s just difficult to play the game) for the first reason, such system requirements are not suitable for simulation games.
and fourthly, the gameplay is too boring and difficult. The first is a protection of the level of the system, the second is due to the lack of optimization.
Good luck, well done for deciding to make a game,
but I think you probably didn’t expand your capabilities a little, it seems to me.
