Можете ли вы сказать мне , если есть руководство для этой игры?

All monsters are killed, what to do next, how to complete the level?

There is nothing more to do

the game is a beta and does not have a clear objective, only to reach the special zones and see what happens

the strong point of the game is the encounters, depending on the result of fights or some perk you get a different encounter, for example the angel and the merchant are the most varied, the spider girl makes a difference if you lose by knockout or by an sexual attack (satisfying her), the girl with the cat lets you fuck her if you win.
The game has much to explore in the sense of possibilities and lewd things

Many thanks for the brief explanation.
