Yeah i know this feeling. You can continue your old save files from previous versions. This should mostly work without problems. When i test a new update from the beginning, its mostly stupid clicking, without reading story or looking scenes You can use mouse wheel to boost this. But its´s always the same. First you need to pass the tutorial. There is no skip. Then i use HosSaveEd and change my money to 1000, so i don´t need to work that much to gain money. Finally i have my own guide with the triggering of the events, so i can play more effiency. There is also the possibility to boost corruption by edit the savefile.
Yeah updating this game by some scenes every new version is stupid, but it's the current patreon model all are using. This means, we "never" reach an end of this game, or game comes to some point where it goes to a second part without working the first part anymore.
If you are bored, you can also skip some updates and play later more updates at once.
What save you want? I have start(behind tutorial), start1000(money),500(played to 500 corruption),1000, corruption level 2, 1100, halloweenpartydormclick, libraryeventline,libraryfree and a lot of more from older runs. I mean at which state you wanna enter the game and replay it? You need a clear position to know, what you have finished and what not to have a kind of flow playing this game.
