Hello, congratulations on your submission! :)
The fox is very cute and the dream world levels are eclectic in a nice way. The nightmare realm is properly spooky, even though the spider enemies are less dangerous than the spitting frogs they replace (even the really big spider, which was defeated in a single hit.)
In the third nightmare world I ran along what looked like the correct path to the glowy plant exit the same as I'd done in the other sections but it appeared to warp me right back to the part of the dream world I'd entered from. I ran around off the path (and found that big spider) but couldn't find any other places to go. By that point, I'm sorry to say that I'd started to feel a bit too nauseous and felt I should stop playing. :(
