the games progression is horrible compared to the OG. it's all random and RNG which is such a horrible idea. RNG can be fun but when the entire progress is revolved around just praying that you get a door that takes you to an area where you get an item is such a horrible idea.
the OG game was very straight forward and you could meet everyone and even the secrets were in the same spots. In yume nikki all the secrets are in the same spots it helps you get further.
imagine if yume nikki's doors were randomized- and everyone time you thought you were gonna get to an old zone you liked before it just takes you to a random place. that would get extremely frustrating and also borining quickly.
another thing with this game is the dev confirmed that he made the boring levels much higher on the RNG pool to get so most of the time you are just exploring the same pool or maps over and over again.
