Haunted House II is challenging, but it's not polished enough to merit an average grade. Graphical break-up, hit-and-miss collision detection, and inconsistent speed all hamper the action. One minute you're flying around the screen, then suddenly you've slowed to a crawl. Sound effects include footsteps and thunder, but these are sloppy. Haunted House II 3D does deliver in terms of challenge. There are two houses to complete, and just trying to finish the first one kept me playing for quite a while.
