Firstly, what was wrong with Still Life? It was one of my favourite games of all time! A bit gory and sad perhaps, even twisted; true, but still a very gripping and well-done game (except for abrupt ending).
The setting of Art of Murder is very similar, in that it is a female FBI agent investigating a serial killer; but that is where the similarity ends. AOM is not nearly as "gory" or sad as Still Life, it does not dwell so much on the actual murders, as that it focuses on the story and gameplay.
I actually found it a very pleasant game to play. The graphics are quite nice, the user interface intuitive and easy to use, and the puzzles weren't too hard. There was just the right amount of tension in the story, to keep you interested, and the story remained interesting, although I did sort of guess "who done it" quite close to the end.
I don't understand how anybody can say that the interface is awkward. Your mouse turns into the cursor you need to use (rather similar to that of TLJ where "look" or "take" is concerned) and you use your PDA like in countless other games.
I also don't understand what a "slow cursor" would mean. (Does your computer comply with the minimum specifications for the game?)I use a gaming mouse that I usually set to considerably faster than a standard mouse, and it moved at the standard speed I normally use, for me. Also, if you find the character's walking speed too slow (I do) you can set her to run by double-clicking. I found her to move sufficiently fast in running mode.
Like posters above have mentioned, it's a point and click game, so you basically just double-click where you want your character, and she runs there. I personally found the control system easy to use.
