Got my copy two days ago from Amazon's pre-order. Am still in the playground and level creator, which is kickass. So is the credits roll; it must be the longest ever.

Now Maxwell in wings or a jetpack and tornados/whirlwinds stay put. The latter are a container and shoot stuff much better (persons, cows, houses, cars, nukes, fog, radium, etc.) Weapons get manier shots. UFO is now a nonlethal container.

Maxwell can't interact with anything unless he's within a few feet. You have to click on icons for every deed now.

The range of smart aggressive monsters is now one screen. There seems to be no cure for stoning, but there's a grow ray.

Rainbows, black holes, and meteor showers now do a show. You can make anything, even a rainbow, glowing with something radioactive. Black holes now grow and kill everything with radiation. There still is no neutron star or white hole. Alkali metals (only Group I) now blow up when wet.

Field gun is no longer Howitzer but some old cannon.
