Stuck on all purple clovers for ages now. Once, a silver mutation popped up, and because I'm an idiot, I got excited and put it into the museum and waited for all the others to show up. Nope. Looks like that one was just a fluke. Still waiting for a second silver mutation, argh.
Well, I finally got some of the bonus rounds after getting the match 3 games, and the Lotus Esprit game doesn't work. The preset squares are wrong, so the round can't be completed. Disappointing after finally getting those bonus rounds.
The zoom isn't working correctly. On some images (for example, the California games surfer) when you zoom in to look at the arms, the little reference grid moves completely off the panel so you can't see them both at the same time (kind of defeats the purpose of zooming in). Also, I agree with others that the match 3 is too hard. If there aren't enough opportunities to match 4 - which is decided at random - then you just can't win the level. I've played twice now to try to unlock, and I'll probably give up with this game altogether if I can't get past the level soon.
