Here are my feedbacks on the games, in random order:
Halfling Quest:
I've enjoyed this game, it has very nice graphics, and there is enough motivation to restart/finish it despite of dying.
It's a pity that the game screen is so small. Additionally I would have wished to have a skip option for the introduction - watching it every time after restarting got a bit boring; or even better: to have a button that takes you automatically back to the screen of the game start (without the introduction).
Don't Get Squished:
It's a very funny idea - and a rather unusual game for AM. I (and my children) had fun playing it

What would increase the motivation to replay the game or to put more effort as player, is some kind of score system - then you could also compete against family members or friends.
Frozen:
I think your puzzles are quite creative.

You have used funny items in this game that made me jiggle.
If you put a bit more effort into your graphics (no need to be a great artist, but draw some simple furniture for example instead of mostly using strange spots), I'm sure that your games would gain a lot more enjoyment.
Unfortunately the game was a bit too short.
Galactic Snowballs:
It's an interesting game, and a promising beginning of a longer game. I've enjoyed it, but would have wished there was more to come.
Just as a sidenote: I've experienced a Dialogue error after pulling the lever twice, I'm not sure if it's only me, or if there is a bug.
I hope you make it a full game, I'd like to play it
Twilight Of The Idols:
Wow, I was very surprised about that game of professional quality! There is a very impressive atmosphere and great graphics! What can I say? Really great game!
It's quite understandable that it ended rather abruptly because you didn't have enough time to submit a full version of it. I really hope that you will continue to work on it, I'm definitely going to play the full version!
Freeze:
I've enjoyed this game very much! It has great graphics, and a lot of puzzles that are not too easy, but still solvable without using a walkthrough. So the difficulty level was quite right (for me).
I would have wished a clearer ending (maybe sounds of a siren or sth like that). When can we escape from prison?
The Cube:
This was the only game using the panorama plugin, and I think it added a lot to the enjoyment of the game.
Being a science fiction fan, I liked the game idea and story, and enjoyed the graphics a lot! Wow!
The puzzles were partly too difficult and less logical for me - brute forcing a 4-digit code twice - okay. But I had some problems understanding the traveling method despite of the text on the computer. Probably a little more or clearer in-game hints could have helped me.
