6 Awesome Indie Games for $10, or $5 when you share on Facebook

I really don't like these kinds of deals with sharing on facebook option. It just feels so scammy to me. But this one seems good since I I found many positive comments on facebook for them.
So they have 6 absolutely awesome indie games (Bob Came in Pieces is an excellent game.) for $10 or $5 when share on facebook.
The games are:
Aztaka
City rain
Puzzlegeddon
Bob came in pieces
Vizati
and Lylian paranoid friendship

This deal ends on 6/20
