Here's my thoughts:
As far as fun goes, the mechanics were pretty good, but nothing stood out to me about it. The puzzles failed to explore the mechanics fully, opting for an easy, throw workers in this direction then that direction. The movement itself was, of course, flawless, but it failed to make itself interesting and creative. My rating: 4 stars.
Not a whole lot of innovation going for this one. Sure, the game worked great, but it didn't bring anything new to the table. My rating: 3 stars.
The theme was... not that great this year. It left a lot of people using pretty much the exact same game ideas, and yours wasn't that different. However, it did fit the theme to a T. My rating: 4.5 stars.
The graphics.... Well done, my friend. Well done. Hats off to you. It looks amazing. My rating: 5 stars.
The audio was pretty darn good, although there's no praises to be singing about it. My rating: 4 stars.
The mood was great, although a variety in the mechanics would have greatly contributing to making the mood complete. My rating: 4.5 stars.

Overall, I think that this is a very good execution. For Ludum Dare, this is absolutely a quality game, and holds some of the best qualities of a successful game. Unfortunately, it didn't have a whole lot of innovation to its name, and the mechanics lacked the variety and intrigue to make the good qualities truly stand out. My rating: 4.5 stars.

Good job, good luck, and happy game development!

Thought this was really well put together! Good mechanics, nice graphics and effects. Overall really nice.

Nice mix of theme, gameplay and story and overall very polished and complete!

ARGHH I HAVE TO WRITE A GOOD COMMENT AGAIN. RRRRHHHAAAAA

I have mixed feeling about this game. As Koala Squad noted, the puzzles were a bit lame (this is a problem I have myself!) The monsters were more skill-based than puzzle-based. However, the mood and art were great, the music a bit boring but good. Overall, great game! Good job.

Great job. I liked the mechanic of throwing the workers and the weighted platforms were fun. I'll agree with others that it gets a bit repetitive but as someone who had the same issue I know how it goes. The look and feel are great, love the lighting. Overall I really enjoyed playing it.

Cool game. The puzzles could use some work and I would like to see more combat, but overall it is a good game with tons of polish!

Wow! Great game! Theme, story and enviroment are awesome! The mechanics are good but maybe a bit repetitive, all the time is throwing workers, maybe with a different variation in actions, or new enviroment props that you can interact can improve the gameplay... reminds me The Swapper! Congrats! Well done!

Really cool puzzle prototype! Loved the atmosphere.

Awesome submission. The atmosphere that is conveyed by the game is really great. The idea to sacrifice workers to clear the way and then leave the facility fits perfectly into the theme. I think the game stands out because of its simplicity and is high in my own ranking of played jam games!

Exceptionally good work! Amazing art and effects, very well fit together! Nice!

Great work! Great polish, great use of the theme, loved the weight mechanic. The throw seemed a bit clunky to me, though. Holding to charge didn't seem to scale (or maybe I just held too long each time, but it's hard to tell without feedback). I think this is a good, solid base to build from, though!

very enjoyable. well done! Thank you for your submission

Great game. You absolutely nailed the mood, I loved the feeling of darkness and light that you managed in this game. The sounds were also awesome and perfectly matched the mood. I liked the interesting puzzle elements that you introduced throughout the game, it made it a much more experience than just throwing workers at enemies. I do wish that I had been able to save more workers though. At least for me I had to throw every last one at the enemies to finish the game, so I felt less bad about the sacrifice because the game forced me to do it. I think that if I had been able to save someone other than myself I would have felt worse about the ones that I left behind. Overall this is an awesome atmospheric game, I am really happy that I played it. Great job!
