I really enjoyed this game in Introcomp, and the finished version is even better.
This isn't a grandiose or intense game. This game is just like an Agatha Christie story, with great attention to psychology and detail.
It manages to have a lot of material you have to plow through without feeling too much like lawnmowering. The author has a lot of context-sensitive programming with inventory-based puzzles, and that's what gives this game a good 'choice feel', if that's even a phrase.
You are at a hectic Christmas Eve dinner and Grandma's ring turns up stolen. It's your job to track down the culprit before the police have to be called.
Overall, this was my favorite Spring Thing game. Well done.
