500 Gifts Given Celebration Train! [levels 0-5] (Now with extra gibs)

Hello again everyone! Recently, I reached the humble milestone of 500 gifts sent. I figure the best way to celebrate is with a train, right? So here are ten cars with what I like to think are some pretty decent games. A few of them are even unbundled. There are 2 giveaways for each level from 0 to 5. Quality ramps up as levels do, but I think I've included something worth playing for everyone.

There's also a small jigaw (AND I MEAN VERY SMALL IT'S 9 PIECES FOR CHRISSAKES IF YOU CAN'T SOLVE IT I DON'T KNOW HOW YOU GET OUT OF BED IN THE MORNING) first, to root out the bots. I know jigidis tend to turn some people off, but I promise it'll be worth the 20 seconds it takes to solve it.

Finally, there are discussion questions on some of the giveaways, since I prefer conversation to simple 'thank you's. You're not required to answer any of the questions, of course, but if an answer pops into your head, don't be shy! Heck, even if you aren't high enough level to get to the end of the train, feel free to continue anyway and answer some of the discussion questions.

Without further ado, Let's get started!

EDIT: Turnout had been GREAT so far! Thank you all for responding to the discussion questions- It's been really interesting reading your answers!
Here are a few extra cheapy gibs for you (level 0 so everyone can enter):

Jet Racing Extreme
Face Noir
Bit Dungeon 2
