At first the two stories feel barely connected, meaning you need to put in the effort twice to connect with the protagonists. The puzzles are all logical for the most part so far, and mostly feel clever and familiar.
Calling "Candle" a point-n-click adventure game is a bit of a stretch, as there is no pointing and clicking, but the mechanics are more akin a puzzle platformer. Having said that, it will most likely appearl much more to the PnC crowd with its relatively difficult puzzles, an inventory and puzzles spanning across multiple screens. Being about halfway throug the game, I am very much enjoying my time with it. Even thought the game has a limited set of mechanics, they are being employed in a varied set of ways, requiring some creativity to progress. Some puzzles are a bit obtuse, with some progression artifacts being hidden a bit too well. There is also a "flash" mechanic, and its use isn't entirely intuitive (although in hindsight always fair, with exception of the tutorial), resulting in the familiar point-n-click ritual of "trying this thing everywhere". The story is nothing too exciting, but enough to tie everything together. The cut scenes are well done and the world feels pretty consistent (if you want an impression, you can take the screenshots at face value - what you see is what you get). I really recommend this one if you are in for a game that feels like a more challenging version of Machinarium, and that invites you to experiment in order to progress.
The game was ahead of its time, and I believe it still holds up today. Expect an FPS horror game, and it will not disappoint. Don't play it right after any of the newer Dooms expecting a similar experience, because it will feel slow and dated. The platforming can be a little finicky and frustrating some times, especially for the completionist that wants to explore every nook and cranny. As a game, for the time, I think it is really great. I personally don't have a strong opinion regarding the vanilla vs BFG edition. Just pick one, and enjoy it.
If the visual style appeals to you, then this game is probably for you. I would consider it more of a sequence of espace rooms rather than a point & click adventure. Having said that, there is plenty of variation in the puzzles. Nothing that will make your brain hurt, but not too obvious either. There are a few action sequences, too. Don't expect a plot, just some absurdity, and you should have a good time.
