Christmas Night is free on IndieGala

https://freebies.indiegala.com/christmas-night

The Plot:

The moment the little girl had been waiting for finally came. The tree was decorated, preparations were made and the desired wishes were made. Even though you've been good all year, you're going to have to do more to get the gift you wanted and not be on Santa's spoilers list.

- Will tonight go as Vanessa planned? The Christmas Eve she had been waiting impatiently for turned into a disaster for the little girl.

- If you want your gift, listen to what Santa says and do it to the letter.

- Your mother may have left you alone at home, but the mysteries of Christmas will not leave you alone.

Snakebird Complete - Link

This is a repeat.

Snakebird Complete is an indie colourful puzzle game inspired by the classic Snake game!
This puzzle game is all about snake, birds and fruits!
Find your way through obstacles and reach the end of the portal
Eat fruits along your path before you reach the exit portal of each puzzle
Puzzles become increasingly complex as you advance
But no worries! If they can stop one snakebird, what about two or three or more?
Satisfy your fruit hunger and work with other half-bird half-snake creatures to complete the puzzles

The bundle includes two games: Snakebird and Snakebird Primer.

A brief summary from the developers:
Do you like puzzles, fruit and the notion of crossing a snake with a bird for no good reason?
If the answer to at least one of those questions is yes, then Snakebird might be the game for you.
Solve your way through this headscratcher of a puzzle game and help the snakebirds sate their hunger.

Features single player only.

Castlevania Anniversary Collection - Link

Castlevania...now who doesn't know this game, but here's a summary in case you're one of them.
Ever played mario? Mario is one of the first games for the platformers genre and was released in 1983.
But what was mario missing? You can spit out fireballs (magically out of your rear)
No weapons... No swords or knife for you to cut your enemies.
And you had mushrooms and flowers as your enemies. Very PG.
Welcome Castlevania to the scene of platformers in 1986!
Castlevania was a hack and slash platformer, featuring Dracula as your major antagonist.
Instead of kid-friendly enemies, Dracula's monster minions attacks you.
Some grotesque and horrifying (albeit in pixel graphics) gather in hoards around you.
And for the first time, aerial enemies attack you from above! Namely, Dracula's bats!
Personally, I don't recall any aerial enemies in the first Mario Bros.
Back then, vampire related media were also very trendy in entertainment scene, so this game soared in popularity.
To this day, it is still one of Konami's most successful franchises!

This collection includes Castlevania, Castlevania II Simon's Quest, Castlevania III Dracula's Curse, Super Castlevania IV, Castlevania The Adventure, Castlevania II Belmont's Revenge, Castlevania Bloodlines, Kid Dracula (never released in English before), and History of Castlevania - Book of the Crescent Moon

A brief summary from the developers:
Konami's Castlevania Anniversary Collection traces the origins of the historic vampire franchise. Included is a unique eBook with details provided by developers, artists and others inspired by the Castlevania legacy which sheds a fresh light into the world of Castlevania.

Features single-player only.

Purrfect! After installation, only Snakebird Complete is DRM-free!
Sadly, Castlevania Anniversary Collection requires authentication before it executes.
Snakebird Complete can be opened directly from the game exe file without the client active.
One indie game and one DRM Free, not bad.

Unfortunately it's free to play only.

Edit: Free to keep here too now. :)

What? HL2 is paid game.
Free to keep when you get it before 18 Nov @ 9:00pm.

There seemed to be some temporary bug showing it both as free weekend with a 'Play Half-Life 2' button, and as free to keep. Just scroll down to where it says 'Get Half-Life 2' and click on 'Add to Account'.

Apparently not in my region?

I only have an "Add to Cart" button with a price. :(

I'll retry later ...

Edit: Seems to be fixed now. I got it :D. Thanks for reporting!

You can get soundtracks for main game and both expansions too, those are permanently free though. Both expansions looks like have been baked into the main game now, so you got those too.

If y'all are looking for Episodes 1, 2, and Lost Coast, Valve made the creative decision to move those to the Tools category.

I am currently super not sure if Half-Life Deathmatch: Source is also subsequently attached. I'm certain that was part of getting Episode One back in the day, and would guess that hasn't changed unless it's not part of this thing specifically.

One more thing: HL2, Episode One, Episode Two, and Lost Coast can be played DRM-free if you like. There's also the pre-anniversary versions that are the ones that were still compatible with older machines, if you'd like to know.
