I'm pretty disappointed in this sequel even though its a demo. The physics object system with scripting and such that you implemented is cool, but it could be streamlined a lot. I want really simple prebuilt pieces like a switch which activates a trapdoor or a switch which activates a rotating object - to do each of these very simple things takes several steps.
My main concern with this game is that it appears you have taken out the good/evil buddy interaction system by only allowing negative actions towards the buddy as far as I can tell. This good/evil system was the central motivation for player actions in the original game, and now it is gone. Maybe this is only for the demo? In any case it was a very poor choice to remove such a central and cool set of features.
Without this dichotomy, the mood or reactions of the buddy become meaningless and it becomes less of a buddy and more of a ragdoll on which to beat on mindlessly - the money gaining system becomes tedium.
Also you were pretty over-the-top with the advertisements for the full version - the main character randomly spits out an advertisement message to purchase the game? This is annoying and makes me want to buy the full version less. Aren't the very obvious links in the in-game menu and load screen enough?
In all this demo really turns me off to the idea of paying for a full version - the features I was looking forward to are gone, and the new features are implemented in an overly convoluted manner.
