Need help finding free coop games to play with my mom.
I wanted to play a few coop games with my mom and thought of portal 2 but we decided that it would be better to start with free games if we realize that we don't like it. She has never played any pc games so she'll have to get used to WASD first lol, so if you tell me suggestions, please say games that are mechanically not the hardest and mainly focus on puzzle/riddle solving (like portal 2). Thanks.
