However... why oh why do you use F3 for help when there is no suggestion of that button doing anything unless you a) hit it by accident or b) quit playing and RTFM.
Option a was what happened to me, and only then (after several hours of playing the demo) did I found out about the important things like 'bashing objects' ok, so this made me replay from the beginning again to attempt things properly and perhaps I got a slightly greater taste of things, but it does feel odd, and not so helpful. Definately could be made better there i.m.o.
F12 seems to be a far more sensible option for continuity reasons. It is also the first thing I tried pushing when I wondered if there were extra keyboard controls - but got nothing so cast that notion aside until I chanced upon the F3 page accidentally.
The game itself is fantastic though and the Demo is excellently done. It provides plenty for you to get a feel for the game and definately leaves you wanting.
I can't tell you how many demo's I tend to play but there have only been a handful in god-knows-how-many years that have made me *really want* to purchase the full version. This is one of them. The last one was about 3 years ago. (ThinkTanks by BraveTree - now part of GarageGames)
There are a few obvious exploits most of the ones I noticed have already been mentioned, but there's also the ability to 'save' right before examining the contents of a barrel/chest/whatever. Only a few chests etc have fixed items inside, so if you don't like what you see.. you can just reload and check it again.. repeat until you find something you want. It can be a bit tedious, and defeats the fun of the game, but it's very easy to do. There are also several more easy ones involving messing with saved game files, but perhaps I shouldn't post about them here

Anyhow.. I'm off to get the full version.
