They are often quite small, and blend in completely with the beautiful background artwork. The only two times I was stuck for more than 15 minutes were when I could not find an important item. Graphics, Sounds, etc. Graphically Sanitarium looks excellent. Despite using only a 256 color palette it often looks better than many a high-color game.
Locations are varied from drab, dark, and imposing, to bright and colorful.
The graphics are all detailed and nicely drawn. Everything looks like it belongs together. Animations are equally good. Player and non-player character movement, with a few odd exceptions, is fluid and believable. The sound is also exceptional.
