NOT recommended, unless you're a completionist ...and want to torture yourself.
This is a non-point & click Broken Sword game. The controls are really wonky, even after adjusting them to the typical WASD setup.
You waste a lot of time on box puzzles, as others have mentioned. The "stealth" sections are extremely tedious, frustrating, and don't add to the story.
There were two points in the game that really drove me crazy. At one point, while dungeon-crawling, I missed an item at the very beginning. Yep, you guessed it, no way to backtrack! I had to grab a save file to continue. Secondly, there was a puzzle that required you to check your notes. That was the ONLY time I found myself having to look at the notebook, so it was the furthest thing from my mind!
The dialogue and videos are NOT skippable, so have fun if you have to repeat sections because you missed your window of opportunity to not be killed. Those windows of opportunity involve paying attention to the action buttons and pressing it when required. Most of the time, I was too involved watching what was happening in the video only to realize I had died, because I didn't see the action pop up. Sigh.
And the ending... boss fight, really? Another pointless section!
Not sure what they were thinking with this game compared to 1 & 2 (which I enjoyed), but I was quite pleased when it ended... That says something.
