-Seriously, '''Massive''' spoilers ahead. It would in your best interests only to read this when you reach a point where despite your best efforts, you cannot win.
Many, many years after the creation IVAN, I have decided as to also add my 2 cents on the topic of how to progress through Ivan. Despite me being generally new around the community, I believe even the best of players can learn something from this. It also will be a compilation of several pages of other work, so if you're ever feeling too lazy to search up a specific page, you can take a look here. This is meant to be a generalist guide detailing my opinions on literally everything and tips/trick for progressing through stages. I will go through each topic with its corresponding subtopics, then add a unhelpful TL;DR for lazy people. This guide doesn't not contain exploits, save scumming and code modification, which I don't bother to link as it completely takes the fun out of the game (I consider exploits are addressed like this: If the devs knew about it, would they allow it?)
