It´s weird how the finished demo has become different from the original idea. The greatest contrast is in the intended rhythm of the game: I had in mind a very slow-paced, zen game. Instead, it is now close to an "instant gratification" game. Not so much of a challenge - it´s very difficult to get a game over screen - but still fast paced.
I´m not sure that´s better or worse than the initial intention, but maybe that´s what a "casual non-game" is supposed to feel like. Almost like gardening for the Popcap generations.
