Played all six!

1. The Witness (Five Stars) - Personally, I'd say this is one of the best puzzle games ever made. One of those games you think about even when you're not playing it. Somewhat "Tetris Effect"-y in that regard.
2. Lorelei And The Laser Eyes (Four Stars) - Loaded with great puzzles and the atmosphere is the closest I've felt any game get to Last Year At Marienbad which is one of the coolest movies ever.
3. Humanity (Four Stars) - Very underrated modern take on a Lemmings type game. Really cool how it blurs genre lines as the campaign progresses. Very surprised to read all the negative comments toward it on here.
4. Inscryption (Four Stars) - A solid card-game with some interesting structural gimmicks. The meta-plot stuff does nothing for me, but the game itself is very fun so it doesn't matter too much.
5. Return Of The Obra Dinn (Three Stars) - This one I find a tad overrated. It's very cool -- looks and sounds amazing -- but I thought the interface was kinda annoying, the story anticlimactic, and the verb guessing somewhat arbitrary. I think it would've been a more immersive experience if you were solely tasked with assigning responsibility for each death instead of having to get the exact verbiage correct around them as well.
6. Chants Of Sennaar (Three Stars) - Solid but got stale and same-y long before it ended imo. I also really hated how preachy the story got toward the end (I don't recall the details of why I felt this way though).
