You have to give games away to level up.

By creating giveaways. ;P

nope. nobody knows

Start by killing some trash mobs and doing some fetch quests around town. Then work your way up to clearing the wolf's den, the alpha mini-boss there should net you some decent XP and loot allowing you to venture out and explore. All up to you from that point on!

But seriously, it's a site called "SteamGifts". Wouldn't it be a pretty good guess that you level up by creating these "steam gifts"?
