I love point-and-click adventure games and have played loads, and Gray Matter is now one of my most favorites. That's not to say it's perfect though, but it's defintiely one of the best.
- beautiful art
- great music
- a well-done and interesting story, if a bit cliche and cheesy (in an addictive I-have-to-know-what-happens-next sort of way)
- a unique and fun gameplay mechanic with magic tricks, which had me wishing I could do more with it (hoping that if there's a sequel they expand and enhance this feature! it was a lot of fun). I've never played, or heard of, a game featuring a magician (as in, a stage magician, where the magic isn't really magic) and it felt different and exciting and was a lot more fun than I expected!
- the puzzles feel intuitive and fun but still provide a challenge. I really, really like the implementation of highlighting locations depending on what can/has been completed there. The progress list was also very helpful for the once or twice when I would get stuck and not know what to do, and be able to suss it out based on what my progress list said was only partially completed.
- the quality of the voice acting varies, and took me out of the game a few times when it made me go "huh?". Occasionally a character said something in an odd inflection or with no emotion. It reminded me a lot of Cole Phelps interviewing people in LA Noire, where his reactions didn't always fit the technique choices of 'truth', 'doubt', and 'lie'.
- the animations surprised me by being lower quality than expected. I've recently replayed The Longest Journey, a game that came out in 1999, and Gray Matter's animations reminded me a lot of TLJ. I guess the screen shots made my expectations higher? Certainly not awful, but not what I expected from a game in 2014.
- I experience no bugs/glitches EXCEPT one that effectively prevented me from continuing the game, forcing me to reload a save from hours earlier. I recommend making at 2-3 saves per chapter and keeping them, just in case. This was the only time I was forced to consult walkthroughs, in order to try to figure out what went wrong. Eventually determined it was not necessarily due to me but something just went wrong in the game... I suspect I did something in an odd/unexpected order and messed something, a la King's Quest. Don't expect this to be something that happens often though, as when I looked into it it seemed like a rare problem (but it's still a problem that exists, and a big one at that).
I got the game on sale for ~$3 and felt like I got way more than my monies worth, honestly. Even with what I consider to be 'cons', I'd have happily paid the full price for the game and am recommending it to my friends. I really hope there's a sequel someday!
