Finish my IDEAS ples,
What about you recreate some backroom levels with the game being a lil bit graphic with the player's animations
If you don't know how to recreate some levels, I'll just give you an example:
To recreate backrooms level 1, since according to google it is just the random appearance of wall being able to leave gaps for the players to hide or smth,
you can just create a empty moving blueprint that creates a dynamic blueprint which if it stops moving it will create a wall from the backrooms which should be smaller than the dynamic wall leaving enough space to slightly prevent uncrossable gaps
Also, about the animations
Just do it, it's simple
