The concept quite interesting, but there are some problems:
1. It gets really repetitive after a while.
2. Timer doesn't fit the game style and isn't engaging in any way. I understand you wanted a scoring method, but time pressure to click previously memorized places is simply not fun and not puzzle-like either.
3. It doesn't look good. I don't mind minimalist or retro-like styles, but from the distinct font sizes in the menu (Part n° vs. Score) to Rules' background parchment which doesn't fit with the general theme, I feel like there could have been better stylistic choices.
All in all, it is a good game, and it had me entertained.
Oh, and apparently the Silver Cup medal isn't working.
