Just curious as to what the main differences are between part 1 and part 2. As I was playing through part 1 and then started part 2 and noticed it started at a specific spot instead of after where I was in part 1. Is it just more content in part 2 or is the story differences in part two that there wasn't in part one? If the story is the same but with just added stuff in part two then I'd rather just play part two instead of having to repeat the story but if there are differences to the story then I'd rather experience both that's why I'm asking

Hello. If you for example had Part 1 and played to the end before buying Part 2, then when you purchase Part 2 and start from Part 2 it should start you where things left off in Part 1.

If you didn't get to the end of Part 1 before purchasing Part 2 then my best advice is to play through the whole game but skip the scenes you've already seen with the Ren'Py skip feature.
