Hamilton's Great Adventure has an interesting stylized visual look to it. Hamilton looks to be a frumpier looking Indiana Jones, complete with brown jacket and fedora, while the lands he treks through, South America, the Himalayas, deserts and even a lost continent, are full of color and life, even if the only things actually moving are the parts on the gameboard itself.
I guess a lot of that had to do with how well the backgrounds to each of Hamilton's levels sold the overall feel for the area. Whether it was the jungle-tops that you are suspended above or the tops of massive stone buildings under your skinny walk-ways, the effect of being high up and having to trek across traitorous passageways was really effective.
The game's sound also did a good job of selling the feel of the different types of levels. While all of the background tunes had that heroic feel to it, they also seemed to fit in the different environments in which Hamilton and his bird, Sasha, found themselves.
Outside of the levels, the game takes on a comic-book style as an older Hamilton regales his granddaughter of his adventures. These scenes also feature text-based dialogue with some mild voice-acting not really reading the text, but giving off sounds, or reading some of the words in order to give a feel for how the dialogue should sound.
