Honestly this game was amazing, I have never played Yume Nikki but if this game was based on it, I will have to check it out as soon as I can.
The game is so massive, there was a lot of back and forth moments, but repeatedly I thought I had found everything in the game just for there to be whole new areas to explore. I loved the artwork of all of the characters, it really felt like a dream world but that little bit of animation really made them feel alive.
I had a lot of fun trying to find all of the effects in the game, and you did an amazing job.
