This is part of a long series of Adrift games which generally consist of big maps, lots of NPCs, magical abilities, knights, wizards, etc. with traditional adventure puzzles. There have been some exceptions in the series (like a timed game and a small casual game) but this game is in the main vein of the series.
In it, you are on a quest to a magical labyrinth. To get there, you must first explore a forest, a strange and unusual world with things like (big spoilers) (Spoiler - click to show)cars and asphalt, and finally the labyrinth itself.
There are usually 4-6 puzzles available at each moment, with not a lot of red herrings, so it's not too hard to solve most puzzles by experimentation, especially as there are a lot of hints given. On the other hand, each area has a puzzle or two which would be pretty hard to figure out without help. Sometimes implementation is lacking, like a (Spoiler - click to show)puzzle piece where (Spoiler - click to show)PUT PIECE ON PUZZLE or PUT PIECE IN PUZZLE don't work but (Spoiler - click to show)FINISH PUZZLE does.
Since each area has a puzzle that's hard due to either being a tricky puzzle or rough implementation, this game can take a long time to finish. I used a walkthrough for most of it. If you do do so, I'd recommend stopping once you get some spells and enter the labyrinth, as there's a fun segment that isn't as hard as the earlier parts and which would have been more fun without the walkthrough.
