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.
How will you do that if all adblocker devs will get sued and because of that no safe-to-use adblockers are available?
Are you going to download some unknown shady binary from tor tor or other shady sources to do that?
For anyone from german courts reading this, if you pass that stupid ruling, you might be responsible for all hacked devices that got hacked over ads and/or over shady adblockers. People will not go after the ad networks, people will go after you personally. Because the whole DMCA usage is an overreach to begin with.
