This is an interesting little game. You start out with the option to choose between two characters, and you can either play one plotline through to its conclusion, or you can jump back and forth between the stories at will. I found that if I was stuck on a particular puzzle, I would hop over to the other character for awhile to clear my head.
The puzzles are incredibly easy, almost to the point of being too easy. If I was stumped it was either because I was over-analyzing the situation, or it was because I failed to pick up an item earlier in the game and needed to backtrack.
The hand-painted character designs, locations, and background art are completely unique and absolutely beautiful. I would recommend playing through for the visuals alone.
I also really dig the musical score.
Navigating around each location can be a bit of a slog, but my husband pointed out to me that double-clicking will expedite your characters' movements.
There is a fair bit of humor, more so in Shay's story than Vella's. Make sure to talk to everyone, examine everything, and to use each object with every other object/person in order to get all the flavour dialogue. The spoon and knife are particularly amusing.
The one thing that kind of spoiled this game for me is the story. I really like the mixture of sci-fi and fantasy elements, and the brain-twisting continuity implications of Act I's resolution, but I was so turned off by Vella's plot that it started to sour the rest of the game. I guess I'm just bitter they couldn't come up with an interesting maguffin for her that didn't involve violence towards women of the worst trope kind. (I honestly didn't care much for the portrayal of the other females in her plotline, either.) ::sigh:: Although, my husband played through the game, too, and he thought both stories were pretty well balanced, with an overarching theme of teenagers rejecting outdated authoritarian policies in favour of thinking for themselves, and a subplot of contrasting physical harm with emotional harm. I guess it's subjective, but it still left a bad taste in my mouth.
Overall, I would rate it a 7/10.
