That's OK, I'm here to help. What you want to do is take that rpa. file and put it in the "game" folder of the larger Our Life folder. For the mac version, it's tucked away a bit, but I can show you how to find it. Once you find the game folder, it should be: Contents > Resources > autorun. Inside of "autorun" should be the "game" folder. Put the rpa file in there, and then try to boot up the game. You'll know it worked when you click on the "DLC Info" in the top left corner, and it should show the DLC as "Installed". That should work, and if you need anything else, just let me know. Thanks for playing!

You need to download the base game first before you can use any of the DLC. There's a link here on this page that will take you to where you can find it for free here on itch.io. Once you have that, the previous instructions I sent should guide you to where you need to put that "dlc_step_1.rpa" file. If you need more help, just let me know!
