Getting stuck on a sliding puzzle while playing Professor Layton on the DS jarred a memory of a PS2 game that featured some sliding puzzles-but I have no idea of the title of the game, nor does Tune. I'll list some things we can remember:
1. The puzzles involved roman numerals and colors, and lining up one or both.
2. A library was involved in finding these puzzles.
3. Unsure if they were required to progress the game. Don't think they were.
4. It may or may not be an RPG.
5. There were multiple puzzles, each increasing in difficulty.
Google has not been my friend in my quest. I know I'm going to feel like a dumbass once I find out what game it was.
Any help?
