[PC] Thimbleweed Park (2017)

How:
Got from a friend's Humble Bundle.
Note:
I got the repair kit from the hotel room by exploiting a bug that would leave the door open, without having the ghost zap the electric lock.
Pros:
- Nice graphics
- Several references to classics in the form of puzzles (e.g. the sheet of paper flying away)
- High degree of (at least perceived) non-linearity
- Nice multi-character puzzle design
- Memorable clown character
- Too many red herrings
- Nice puzzles
Cons:
- Music doesn't loop well and is a bit repetitive
- The in-game radio is terribly annoying
- Unskippable dialogues
- Some unresolved threads

The navigator's head makes an appearance!

[PC] Sanitarium (1998)

How:
Played the demo when it came out, finally bought it during Halloween sales at GOG.com.
Pros:
- Cool isometric view
- Nice music fitting well the creepy mood
- Plenty of cut-scenes
- Engaging story with a slowly unraveling mystery
Cons:
- Some game-breaking bugs and crashes
- Puzzles tend to be sparse and easy, they mostly serve to move the story along
- Lack of dialogue continuity; the character reacts to dialogue in a fixed manner even if he already has the information he needs

[PC] The Whispered World (Special Edition) (2010)

How:
Read about it on Adventuregamers.com, got during a Daedalic sale at GOG.com.
Pros:
- Awesome background drawings and in-game animations
- Puzzles are quite clever in general
- Very nice music, although a bit monotonous
- Nice, relaxing mood for the most part
- Quite lengthy and adventurous
- Nice unconvential puzzles to be solved using Spot's transformed versions
Cons:
- No wide screen, a real pity
- Stuttering animations, usually at the beginning of each scene or location
- Glitchy sound in the dialogues
- A couple of annoying puzzles (e.g. move around rooms in the Asgil's city)
- The main character is unlikable, unhearable, and depressing for the most part of the game
- Some puzzles can be solved by accident, destroying continuity
- The clock puzzle in the oracle's hut was automatically solved for me without me asking for it
- Lots of pixel hunting
- Some game-breaking bugs (e.g. character stuck in the background, door does not open, etc.)
- The cinematic parts among chapters do not live up to the rest of the game

[PC] Toonstruck (1996)

How:
Heard of it since forever, played it on ScummVM.
Pros:
- Great graphics, animations, and many funny cut-scenes
- The game manages to find a balance between cute/cartoony and downright odd/violent
- Excellent voice overs, fitting music and sound effects
- Well-balanced puzzles, many of which follow their own crazy logic but are nevertheless very fair
Cons:
- Dialogues tend to be too long
- The few hotspots per screen make the game easier than necessary
- The game starts abruptly with no apparent reason on why Lloyd is sucked in the cartoony world, and he accepts the fact naturally

The scarecrow scene in its "malevolant" version...

...reminds me of this scene from Emerald City Confidential (2009)
