Caterpillar Cowboy
After launching game, I was shocked with so good visual and sounds, especially voice is perfect ;)
This project let's you feel yourself real caterpillar cowboy. Gameplay feels absolutely perfect: to grow you need to get in loop any objects and then you more, then more objects you may eat. I finished that games for less then 5 minutes, but this 5 minutes of gameplay were brilliant!
Great project, recommend everyone try it here: https://ldjam.com/events/ludum-dare/47/caterpillar-cowboy

HyperLoop
Actually I don't like horror games, but this combination of platformer, shooter and horror makes me enjoy gameplay. In my opinion, this game, except good visual, sounds and gamedesign, is very ambitious. There is a plot in this project, and it's kinda interesting, I believe that after release of this game we will see great project with interesting game mechanics and good story

BoreOut!
Yes, at first look, this game has pretty bad optimisation and some bugs, BUT! Where could you throw items in your colleagues except this game?) I really enjoy this project, it's so funny and feels great, actually an idea of BoreOut is really well. And I know that it's repeating of budget cuts, but i'm happy to see this game in Ludum Dare. Great job guys!

Timesaver
I don't think that it's unfair to add my own game to this list :3
Basing on my opinion and players' feedback, I can say that concept of the game and graphics are well. I know that it will be a little arrogant, but gameplay feels perfect, believe. Or don't. Anyway you should try it and feel yourself as a real ninja, who fights with mad scientists using his sci-fi catana!

P.S. If you want us to play your game and maybe write about this in posts like this, leave comments and we'll play & rate!
