Wow.

I leave the project for one day, and come back to find that Jordi has changed four bits in the source code, leading to the fact that at least five more puzzles are now complete. Of the two that are left, one might work (apparently, just about to test it myself :-), and the other is going to be very, very difficult. It’s the microscope puzzle, which if you know the game, you’ll know is very different to all the others, as it involves an albeit basic form of AI.
