Short little game around 30 - 35 minutes at most, really only enjoyable if you enjoy scat content. Otherwise the content is just bland, and imo is better found elsewhere.
Actual combat is easy enough but annoying, since when you lose you are sent back to the start of the game, not your most recent save. Thus it is a lot of redoing the same area if you are trying to lose in each new area to see the lose scene. You could always lose see the scene get the achievement and then exit to title and reload that way, but the point still stands it is annoying.
