Only saves after missions, however building missions remember your building state (this was not obvious to me at first). Super fun, but don't be afraid to seek out on-line help if you get stuck. The save the smarties, for example, is very difficult.
I played through the GoG OS X version and it worked wonderfully. This is a Kings-Quest-like adventure game through and through. The interface is more complex than the game really needs, it is trying to build sentence commands like the old Infocom text adventure games. The VGA era artwork is very well done, and worth going through to see. The story is very good, and to me got better. It seems "standard" at first but has a twist I'll not spoil. I ended up consulting a walkthrough I found on the internet from time to time. I recommend this for all but the most hard-core player. There were a few times I would have been guessing or trying every item on everything. Which distracts from the story. Some of the puzzles seemed too tricky to get without a hint for all but the most hard-core of adventure gamers. A good feature of the game is that you come back to life when you die to try something else (saves loading from death). Overall a charming old-school Kings-quest like adventure I'm glad I played, I had played Sierra's adventure games back when they were released but had never heard of this title, it is a good old game.
