Oh no I think they are great I like all of the characters and the story so far is interesting. I would say that it just feels like there is a lot more to discover with the puzzles. I think the lore is very interesting as well especially the stuff you find as you explore the dream world. Yuri is very fun with her snarky tsundere behavior. Kari is rather interesting (and worrying) with how she has her own dark secrets and her attitude toward the MC. Nanami is cute but I feel we need a little more time with her tbh. As for the MC I do wish they commented more on stuff, that would be my one gripe. I get that they are probably meant to be player character but I honestly think it would help if they commented on stuff in the dream world too.
One thing that I am really intrigued by is the fact that I believe the MC's dad works for the company involved with all the dreamworld stuff so I am excited to see how that plays out.
