Thank you for playing the game.
Yes, most of game here is naturally made in Unity, because Brackeys is known for his Unity tutorials. But I just love using UE4 for all my games.
I do totally understand if you don't like the music. It's inspired by music from games I played when I was a child, and yes the music in those games were really not very good and often had some really weird sounds and often was they extremely repetitive. I know it's weird, but I kinda learned to love that kind of music, even though it's kinda bad.
And yes I could have used more humour in the game, and I do often use humour in my games. But decided not to over use it in this game.
