Really well done, you managed to make quite the innovative use of this mechanic in 3D, next to that you also managed to implement great visuals and a fitting soundtrack and even managed to make it seem as if the meat belongs in this environment :D

In terms of level design i must you created some really cool puzzels here, with more time and levels this really has some potential for an interesting fully developed puzzle game :)

Very cool . I like it!!!

Great puzzles, plenty of good "gotcha" moments that made me reevaluate my assumptions.

Very nice, good puzzles, and nice visuals

That's a very clever idea. Visual effect is so satisfying especially effect on the check point. As a programmer, puzzle game is one of my favorites!

Take some times to play my game with friends!

Cool idea for a puzzle game mechanic, it seems like it has a lot of room for creating  a lot of different interesting levels. The meat sound effect is gross in the best way possible.

First of all your game has a very great gamefeel (the meat feels "meaty ", the graphics are very clean and the clones are easily distinguishable).
Your game has a nice learning curve its not too difficult to get into and gradually builds up like it should. Ofcause the 'difficulty ceiling' is very low because its a jam game made in 48hrs and theirfor doesn't have as much content as other puzzle games, but that doesnt hurt the experience.
The soundtrack is a little boring but blended in with the overall feel and theme when I didn't actively pay attention. 
I have noticed some minor bugs like being able to role the meat back up a block when it didn't fall long enough or a door pushing the meat upwards when closed while moving onto it but nothing gamebreaking. You could consider waiting untill the meat has fallen / the door is closed before you let the player make an input again or make the fall/closing faster so the player doesn't have the time to move again.
All in all a solid entry!
