Link the Thumbnail to steam page? + explanation of levels?

Levels increase as you giveaway games. There are some restrictions on it, mostly that previously bundled titles will level you up slower, and that you need at least 5 entries in a giveaway to count.

Thumbnails? There is already a link to the Steam page, or similar site that offers the game for sale within each giveaway. Just look a bit harder, or read.

You have a point on that but there is still a link on the actual GA page, if you look at the filters at the left hand side you'll see the Store link. But yea I guess maybe it should be more obvious. And I believe the levels on your have is proportionate to how many games you GA.

There is a link to the game's Steam Store listing on every giveaway page already.

was looking for it everywhere but yea, its directly under the pic, down under the section for comments and entries.
