Candy mod is a normal mod with nothing special, but simple addition of some candy versions, which are mostly changed color and basic stats, of vanilla mobs, items (like tools, armor, or new crafting resources), and a biome which simply increases chance of candy mobs spawning
There is a small crafting system, that has one set of basic items and then 1 set of advanced items, even though items are not really special in comparison to any other mod, they do have some op stats for vanilla Minecraft (not including mobs from this mod, which are made to be just as op).
To summarize all items and mobs, there are candy versions of few vanilla mobs, there are 3 candy versions of armor, flying boots, which are recommend with first advanced armor, 2 candy versions of tools and some additional items such as special sword and armor all made from the hardest candies to get, hammer that can help in making of special (OP) drugs, and some blocks like block versions of candy items, and a lamp that is mostly cosmetic, as it is not as good as vanilla torch.
There are also some additional items and details about this mod, which I leave for you to discover
Crafting is really impossible to do without any mods to help you with it, like JEI, so I do recommend to have such mods installed to enjoy this mod's crafting system.
