You right click for inventory, and press ESC for options. Basically, you hunt for items that you need to advance in the game. I never failed to get that all important feeling of satisfaction when I found an item I needed or solved a puzzle. Not once did I feel the game was ridiculous and, overall, was impressed with the cleverness of the puzzles, although in this category I think there should have been more of them. There were only a couple that I can recall, although they were very, very, good the ones that were there.
Graphics are outstanding and really enhance the game experience.
Sound was good, although I sometimes felt certain sound effects were too embellished for their own good. But overall, no complaints here. The sound, like the graphics, added to the game experience. Resurrection is about one man and his struggles against the prince of darkness. If you are looking for a challenging game, do not look towards this one.
