Has anyone here spent time playing on 2 player games?

I recently discovered the site and was surprised by the wide range of free 2 player games it offers, from quick racing matches to competitive sports and even strategy challenges. I enjoy how easy it is to jump into a game without downloading anything, but I am curious about other people’s experiences. Which games on 2player.co do you think are the most fun or addictive, and do you prefer cooperative options or head to head battles when playing with a friend? Would love to hear your recommendations and thoughts.
