There's enough malware on the net to make anyone wary of just downloading something on a whim. You have to entice players into 1. trusting you and your content, 2. seeing value in the product (easier when free), and 3. seeing that it is worth their time and effort.
Screenshots and videos demonstrate that there is likely to be an actual game - and possibly a fun one - and not just malware. Reviews or word-of-mouth suggestions by friends builds trust and user-base.
That is part of why people will not go for just "Click here for pixelboy!" What IS pixelboy? Is it free? A big download? Is it a game or a tech demo? Do I need anything else to run it? What's it like? Think like a stranger and try to answer those questions BEFORE they're asked.
So, tell me about Pixel Boy.
