This is one of the few games that has actively gotten much worse over time. But being connected with Crime/CillianGirl/Catfish is a curse. One one hand the tech they developed for the animations is neat. On the other hand, every single one of their games is a scam and as soon as some interesting content exists they work harder trying to paywall it than they do on the actual game. Not to mention the story rewrite which made the story a lot worse.
Unpack into game folder (where .exe file is located)
Run the game. The first run may be slow, please wait
If you don't have access to paywalled features - press "Log In" button on main menu or "Update Now" or any other sus button they give you, it should trigger the crack
