Hello,
We've been playing It Takes Two on our PS5 for close to two years now. Since we don't play it every day or even every week (busy schedule), we just completed the game last week and I've had a lot of experience in saving the game and coming back in to the same place ... or not 😉 It really is defeating to FINALLY beat one of the boss mobs, only to come back and find you have to do it all over again. Thing is, the game is so danged fun, we bit the bullet and did it again. There really isn't any other game found that is so perfect and fun for two peeps to play together on one PS5. If you know of one, I'd really appreciate you posting here, as we would love to have another game like this one to play. Since we haven't found one, we started this one over again and are finding it just as fun the 2nd time.
On a high note, I finally figured our how to save the game, exit it, and come back to the exact same place when returning to play some more. This is how, and it's worked every time! Use the 3 bars on the right side of your control to go to the chapter selection screen. There you can see where you are in the game and there's a resume button too. From there I hit the PlayStation button, click to the home screen and leave it in the Resting mode. When I come back into the game, it's always where we left off, no problems. I've even turned the PS5 off and found we're still in the same place when we reenter the game.
Hope that works for you too ... let me know.
