Tinkering

Some of your items may be combined via "tinkering" mechanic, sometimes resulting in new, otherwise unobtainable items.

Basics
You can only do so in some safer locations; currently, the following locations have such zones:
 * Cassie's safehouse
 * Condo
 * Milk Farm

Note that most items are consumed on use (unless otherwise specified).

Recipes
Only the following items can be mixed. If the player tries to mix incompatible items, the "that doesn't seem to work" message would be displayed, otherwise, one of the following results would be achieved:
 * Big Fish: Can be put into Bottle to make a Soup (up to 3 dosage).
 * Bottle: Can be mixed with either Small Fish, Fish or Big Fish to make a Soup; produces 1, 2 or 3 dosages, respectively, consuming the same amount of bottles to put in.
 * Cheese: Can be cut with Dull Knife to produce five Cheese Slices.
 * Cheese Slice: Can be put on Weird Fish. After two "are you sure?" prompts and a warning about possible Bad End, produces Cheesy Weird Fish; can only be done once.
 * Counterfeit Pass (any type): You can use it to try and improve the quality of the pass, which would initiate the Nimble check. If successful, would create the Quality Counterfeit Pass, otherwise the pass would be wasted.
 * Dull Knife (never consumed on use):
 * You can try to cut the Weird Fish with it, but would stop at the last moment when it looks at you.
 * You can cut the Cheese, which would give you five Cheese Slices.
 * You can cut the Your Cheese, which would give you five Your Cheese Slices.
 * Fairy Dust: Can be used with the following items to create their enhanced versions (x4 more powerful):
 * Lust Tonic -> Lust Tonic+
 * Stamina Drink -> Stamina Drink+
 * Mana Potion -> Mana Potion+
 * Fish: Can be put into Bottle to make a Soup (up to 2 dosages)
 * Ink Pen: You can use it to try and improve the quality of Counterfeit Pass, which would initiate the Nimble check. If successful, would create the Quality Counterfeit Pass, otherwise the pass would be wasted.
 * Lust Tonic: Can be used with Fairy Dust to produce Lust Tonic+ (provides +80 Lust instead of standard 20)
 * Mana Potion: Can be used with Fairy Dust to produce Mana Potion+ (provides +20 Mana instead of standard 20)
