Current Features of V0.1:

Probably a lot of bugs...

Tools.

Simple enumerator for tools: watering can, scythe and empty hand. Key press is required to equip them.

Durability system.

Tools have durability, currently maxed at 5 uses displayed on the top right. Blacksmith needs to repair them for you to use them after they are broken.

Planting system.

Simple plot that takes seeds and grows plants (needs water before they start growing), which then can be harvested with a scythe, and give petals and a seed back. Each plant type takes different amounts of time to grow. (3 types currently.)

Upgrade for plant types.

Plant types have 5 levels, each level gives 1 extra petal on harvest. Displayed on the main menu.

Ingredient making system.

Currently 2 types of ingredients, powder and mixture. Petals are used in a boiler/crusher and make it's own ingredient + a component.

Potion making system.

Recipes require a major ingredient, a minor ingredient and sometimes extra components. 
Major ingredient: a petal type.
Minor ingredient: a ingredient type.
Components: if any life type is used above, add a solid component, if any sorrow type is used above, add a liquid component.
All recipes can be found in the recipe book.
Cauldron shows at the top what's currently inside the cauldron to help. Can press C over cauldron to clear contents.

Containers.

Ingredients and potions require container types.
These can be bought at the shop, using the dropdown for multiple purchases, will not work if you don't have enough money.

Customer spawn system (basic).

One customer spawns at a time, currently they spawn without delay.

Selling potions system.

Giving customers the correct potion gives you coins, which you then must click to gain the money from. Current order also displays top left of screen, highlighting over with mouse shows an image of the potion.

Measured item spawn system.

Currently have a system where items spawn on a delay to slow overcrowding of objects. Currently quite slow.

Tips system.

To help onboarding, there is a toggle tips top left which when active shows tips when highlighting objects in the scene, such as the boiler, crusher and cauldron.

Save system.

Found in menu, you can save, load and reset your save. Currently no auto-save.
Saves stats of player (like gold, name, level of upgrades, level (although level is not implemented yet)) + items currently in scene.
 When loading, all saved items respawn with measured item spawn system, so may take a bit to load everything in.

Level system (set-up).

Currently have level and exp stats, but they aren't used anywhere yet.
