I do like this as it atmosphere is very strange indeed and the whole film is weird and disturbing. According to IMDb trivia this wasn’t deliberate:

Director Harry Bromley Davenport stated in an interview on the DVD release that he looks back on the film with embarrassment, saying that the bizarre atmosphere of the film was completely unintentional and that there is no deeper, symbolic meaning to the strange, random events that happen, because he and his co-writers were very high on drugs while writing the script and would often throw in whatever random ideas popped into their heads or thought would be neat, such as the panther scene and the toy soldier coming to life. Davenport has also said that despite being unhappy with the film, he is somewhat proud of its reputation for being a disgusting and bleak horror movie.
