Where is the game manual?
Start the game--Press Esc--Poke the keys, they hide the answers to many questions.
Btw the game can be translated into any language using XUnity.AutoTranslator-ReiPatcher, but then the cheat Monkey may not work correctly.
Read the posts, it is full of various tips, recipes and techniques for progressing in the game from experienced and desperate Non-Cheater Mechanics.
I also started without cheats and advanced to level 3, but the game beat me.
Start by evaluating one or more of the girls' traits, even if they're scary. By doing this, you will allow artificial intelligence to understand what your preferences are. AI will take into account your preferences and it will be progress. Many girls are better to skip stupidly. At first, the witch carnival in the game can last several months of game time. Levels will increase, time to reach new levels will take more and more. Cute chicks will come across more often.
There will be many, many sleepless nights
.. and then you will turn on the cheat.
This is a very interesting and very long game.
