I've completed them all now, so here is my feedback:
White Bear Beauty Chlorinde and the Paranormal Parrot by DBoyWheeler
This was a nice idea for a game but, as Shadow1000 mentioned, there aren't really any puzzles, just walking around the house until you find the items you need. Also, I found that the default walk speed was very slow and had to speed it up a lot in settings. The parrot companion was a good character, though!
Wilfred:2088 by HanaIndiana
I love the look of this game and the idea is very original. The puzzles are good and completely logical, the main characters really come to life, despite neither of them being human, and the voice acting was great! Really good job!
A Martyr of Time by Mandle
This game drew me in from the very beginning. It took a short while to figure out what I could do, and how, and I got a bit stuck towards the end, but overall I really enjoyed the game. I just wish it was longer! I'm glad you're working on a full version!
Finger of Suspicion by Slasher
I really like the concept of this game. I think there are a few kinks to be ironed out, like the fact that after a while I was pretty sure I knew who the murderer was but couldn't accuse them because I hadn't found all of the keywords. I'm not really sure what exactly triggered the final accusation screen, either. Overall, though, the idea is really good and I think could be expanded upon to make a really decent game.
All of the games were very individual this month, but one of them really stood out for me so my vote goes to:
Wilfred:2088! A Martyr of Time comes a close second for me, because of it's intriguing story and interesting puzzles, but there just wasn't quite enough of it in the end.
