The graphics are cartoon-like in nature and the style is great to look at. The mouth movements don't line up with the dialogue being spoken, but that fits the entire crude sense of it all. As for the dialogue, outside of being foul, the performances are truly enjoyable.
One place where Hector does somewhat differ from many other point-and-click adventure puzzles is with the dialogue trees. It isn't simply a matter of exhausting all your choices in order to get someone to give you the information you need, rather there are several times when you need to progress logically (or semi-logically) down a path, choosing the right responses to get what you need to know and advance.
The game also features an in-game hint system which is just as lewd as the game itself. Ask how you should proceed, and you'll be berated rather regularly for daring to not go out on your own to figure it out. The hint system really is a perfect extension of the title and helps give the game a more finished feel.
Sadly, that finished feel is rather destroyed by the current Mac port of the title. Going back to that first impression of the game, while that first puzzles is brilliant, utterly disgusting, and a great hook into the game, one of the first things you'll actually notice in the game is a horrendous flicker. The port to the Mac does have a significant bug (perhaps only with certain video cards, perhaps not, and other PC bugs have been reported as well) which causes different parts of the game to flicker on screen. One moment you will be able to see everything perfectly, the next certain items on the screen will disappear, then other items, then the whole thing. Telltale is aware of the issue, but that doesn't stop the title from being an incredibly frustrating experience at times – it seems inconceivable that the default hardware configuration for many current generation MacBooks (and who knows how many other Apple computers) have a video card that is potentially not supported.
