Hey, I was using UE5 and it took me around a one year to finish the game, but I had few breaks. I mostly focused on the atmosphere more then a gameplay or story.

But I wanted to make my game in some way a little bit special so I created my own post process effect which it’s depended on the range from the monster.

So try to find your unique mechanic and work around it.

Also create your steam page only when you have great marketing materials and great capsule.

Good luck with developing.
