Brightstone Mysteries: Paranormal Hotel HD, you'll have some environmental puzzles like retrieving a key from a grate using a piece of copper wire, but I like how they set it up, "Operation" style. If you touch anything but the copper wire to the key, it buzzes and you lose the key and must retry. You'll also have puzzles that require you to overload the equipment in a boiler room to cause a diversion, or to get an elevator working by randomly tapping on buttons. I saw a method to the boiler room puzzle, but the elevator didn't really seem to have a particular sequence. It just seemed very random.
Sometimes you'll have items in your inventory that you can use to further your progress or get past a locked door. If you select an item and drag it to the appropriate spot, you will see a green haze indicating that you have chosen the correct item. A red haze indicates you chose poorly. You have the option to turn the "footprints" button on or off. When it is on, you can see the possible paths you can take, but when it is off, you are all on your own… until you turn it back on again.
Besides the environmental puzzles, you'll encounter slide puzzles, rotation puzzles, maze puzzles and one where you have to align tiles. Most are pretty easy to figure out and are fun, but one or two are a little more difficult.
Overall, I found Brightstone Mysteries: Paranormal Hotel HD to be a pretty short game. It was an interesting adventure, but just not as great as some of Cateia's other offerings. I will say that there's a rather repetitive but hilarious scene where an angry mummy b*tch-slaps a character over and over. It's clearly a repeating animation, but funny nonetheless. If you really like adventures, check it out, but it's not must-play material.
