Maybe not the best minigolf game on the gameplay side of things, but I guess that isn't the main focus. Having got some memories of playing random PC games from CD's wrapped in paper or cardboard envelopes, the graphical style I think is quite spot-on, in that tidy, but featureless way. The filter makes it seem like an old VHS recording of a said game, though, maybe that's the "fever" or "dream" part.
