The descriptions of a heist and the specialist needed never seem to match up. The planner is needed for mission 10, but the description calls for a hacker. Kinda fun though.
The game always seems to freeze up a bit after I choose a side. It makes me miss the first match no matter what, and occasionally just locks on a red screen.
More than one difference per painting would be nice, the ability to click on the difference in both paintings, and the cursor change makes it quite easy.
