I would say this website is very suspicious. If you download anything, try to find the same game from different sources and do a binary comparison if the game binary code is the same.

Website is totally fine as a page listing native games, but you should avoid downloading binaries from unknown sources.

Why? Example:

World of Goo 2 Is not a "free" game. Suggesting to download the game from torrenta is very sus. At least it is a pirated copy, unless this game have some hidden git repo where you can compile the game for free for yourself and it it used. At worse it is a infected copy with some virus/backdor/data stealer.
