Fantastic game!
Most of the puzzles were the perfect difficulty, although I had to pull out pen and paper a few times, and with the clothesline crows I swear I had the right answer at first, but it told me I was incorrect, leading to a few "what the heck" moments.
I know that in some puzzles the rules could have been a bit more explained, but it's not the end of the world. The 100% perfectionists are grumping about it, but trial and error are part of adventure gaming for me.
I play on 1920x1080 and I would love to see the graphics tightened up a bit, specifically in places where there are close ups on characters, otherwise looked great. I love the art style, and the creeeeeeepy moments were certainly creeeeeepy.
Can't wait for more of these. (although I'm sure I'll have to

)
One teeny tiny request: don't release games so late in the evening! (10pm CST here) I was thiiiiiiis close to bed, and BOOM: PUZZLE AGENT. Stayed up an extra 3 hours because of your artistry! Damn you! I have an MA thesis to write! You know your games are like crack!
<3 you, Telltale.
edit: Oh, and I thought the tiered hint system was great. Also I'm not positive, but I think the hints for the 3rd "bug puzzle" were displaying the hints for the 2nd bug puzzle accidentally, because I am certain the patterns it suggested were no where to be seen.
