So far, I’ve played 50 games. On my first Ludum Dare, I only played about 15. So I’ve improved. Anyways, I’ve decided to give some of favorite games (in no particular order) to help you find some cool games to try out before judging ends.
Bipolar

A really cool puzzle game where you use magnets to solve puzzles.
I really enjoyed the gameplay of this game. It was very unique, and I think it is full-game material. I think this may be my favorite game.
Merkaba

A game where you have to find enough crystals to power your spaceship. But you can only turn left!
This was a simple but fun game. There were not really any enemies, but it was still challenging. I think NostraDamon could take this somewhere.
Cylinder

A game where you must get to the end of a cylinder/tunnel, and you get to turn the entire cylinder.
This one had unique gameplay. I would also like to see a full game from this one.
Mustache Armies

The game’s creators explain it best: “Each unit of your previous rounds adds up, replicating all the movements you made when you controlled it. Thusly, a massive army”.
I loved the graphics of this one as well as the unique, innovative gameplay. The sounds were also hilarious. Definitely worth making into a full game.
Of Guards And Thieves

A multiplayer shooter/stealth game.
Unfortunately there were not many servers or players, but it sounds like it is still being worked on, which makes me happy.
ProductionVille

A city builder.
Has room for expansion…
SDFJKL

Words can’t describe this one.
Too innovative to skip.
Potato Dungeon

A fighting game?
I don’t know what to say. I guess you will have to see for yourself 
Well I’m too lazy to add anymore images, but some games you should definitely check out are:
Bridge Crosser
Screaming Cubes
TOOM
My Mini Castle
S.A.M
Tessitron
BASHLAND
Reversnake
And not to mention, my game 😀 XD.
