I would say it depends.
Because I dont know the type of game you are making, I will give you a more generalized answer
No. It isn’t enough. If you supposedly had the game made with your 45k still in tact, then maybe. 45k in the advertising scene may work, if you play your cards right and get a bit of luck, but for a surefire way to get your game popular you need around 75-100k (minimum)
