If the walkthrough don't help (see what
Jstain answered you), it can be because of a bug present since few updates. During the checkup, you need to talk about Amanda's mother, but at some times this dialog option disappear and then you're stuck. Normally there's a fix for that in my
mod ; which so far is the only way to fix the problem.
On the computer in MC's bedroom, click on the "search" icons. There's a choice that should pop-up about tutoring sessions.
If you saw the scene with the three girls sunbathing, there's really no reason for this choice to not appear.
At worse, go back to the beach and go to the sun-bed part. If you're told that there's nothing to see, then the choice is available on the computer ; else, well, you'll finally see the scene, which will make the choice available.
No, it's on the magic island, in the temple on the mountains.
Download the attached file, put it in the "[path to the game]/game" folder (where there's all the "rpyc" files), and it should solve the problem.
This said, this error shouldn't happen, are you doing something special with Ren'py before starting the game ?
Look at the walkthrough ; the link to it is in the first page of the thread.
Hmm, just tried, saves works perfectly (at least for 1.95, and 2.05, I don't have older save availables), whatever with the compressed or the original version.
See right bellow for more information, and
this comment for a possible fix (that you'll have to apply for every future updates).
Please, don't blame the dev for something he's absolutely not responsible. The save have
always been compatible since the very first version of the game ; it's rare enough to be said.
The problem is an, alas, well known one. It come from some
game compressors who, without effective reasons, decided to change the version of Ren'py used by the game. It's what make the saves incompatible with the original game, as well as it make them incompatible with any compressed version that don't change the version of Ren'py.
And they'll always stay incompatible, there's no fix for this issue. So either you restart a fresh game, in order to now have compatibles saves, or you do your fixing move every single time an update is released. The choice is up to you but, once again, it have absolutely nothing to do with Mr.C.
