This game is grindy as hell. My God.
But I am willing to give it a shot... with cheats of course.
For those of you who are trying to avoid the grind a little bit, you CAN use URM. However, in order for it to be any kind of effective, you'll need to know which variables to change.
This game has has a metric shit ton of variables. Like... it's kinda ridiculous. Anyways I am going to provide some basic commands that can be used.
First, unlike many Ren'Py games, the MC's variable in the game is NOT "mc," but is "GG." I.e. To edit MC's money, the variable is "GG.money." This is important because if you just type "money" in URM's search bar, well... Just do it. You'll see. "GG.dict_skill" will allow you to change the MC's skills.
Another important variable to remember is "npc_<npc name>.dict_skill" as this will allow you to edit their variables. You'll actually need to click on the Value box in order to change things like "Exploration," "Love," etc.
I have not been able to find out how to add items to your inventory. I wouldn't advise it anyways because (for whatever reason) the dev decided to add an inventory limit. There may be a way to get around it, but I am scared to try. xD
Anyways, hope this helps a bit.
P.S. If anyone has figured out what names Sophia and Isabella go by in the variables list, let me know. I can't find them. Found all the other NPCs, but not theirs. They don't go by their names (which I assume is because you can rename them).
