It's an interesting concept that lacked some polishing, in my opinion. The 2nd room is the best one; I thought it was clever to have you arrange the stones in chronological order. Unfortunately, I think the other rooms are a bit of a miss. I couldn't figure out the link and had to brute force it. But it's a good base to improve upon. The menu music was a good fit for the game as well.
And congratulations on finishing the game! :)
