is there a cheat for this game? and how do i know how many depravation, guilt, trust and arousal i have
Not really, as for how you know what the points are , press escape, go to items, arrow to chose key items, space bar or enter, then arrows to select diary spacebar or enter to use the diary (If you have picked it up, if not it is on the table in your room) this will show all stat points and as they increase, the drawings on the pages will change a bit, the other drawings can be seen by using the direction arrows to flip the pages if memory serves.
Made changes to the above, it is now entirely too detailed.
The closest to cheating is using the Walkthrough and the Guide, both linked on the OP. So now I'll type my usual bit on gameplay.
The search at the top of the page is your friend, chances are your question / problem has been asked and answered before, make sure to constrain your search by setting the drop down to this thread only.
READ the ENTIRE OP, read the change logs, think of them as a road map to make sure you do not miss any content, keep in mind that scenes / items in later versions of the game may be dependent on finishing scenes / item from previous versions. The Walkthrough gets you through the beginning of the game very well, The Guide will pick-up where the Walkthrough leaves off though the format is now Q/A on how to do things. READ the ENTIRE Gude, you will know what is possible and how to do it, once you have read the whole thing, playing becomes easier because you know what to expect and can go back to the Guide to get the particulars when you reach a given scene. As for cutting down on the grinding, You can chose to "Spend the day with" a character, doing so increases that characters stat by 5 points per day, you can only do this and then go back to bed, Wash,Rinse, repeat style to increase points pretty quickly, make sure to interact with the girls and do some grinding. You will notice additional choices as stats increase.
Cheers
