Shardlight is pretty cool visually and the puzzles are okay. I think I may have described it more positively than I should’ve in the past due to its comparatively short length, but the story/setting isn’t particularly good. In that sense Technobabylon was significantly better done, but it was given much more opportunity to drag.
PS At the risk of making you expect too much out of it, I consider Primordia an absolute must play. More so than any other Wadjet Eye-related game, including the outstanding Unavowed. Primordia is, however, a bit of a save scumming type of game.
