The Backpack Hero beginner tutorial is something that many new players currently need. As a pixelated rogue-like game, the pixel art style is beloved by many players and is highly creative, attracting a large number of player companions. For those who want to experience the game but are not very familiar with its mechanics and gameplay, this beginner tutorial will share the basic operations one by one, helping everyone to quickly feel the fun of this work.

I. Basic Mechanics
The criteria for winning or losing in this game are relatively simple: as long as you reduce the enemy's HP to zero, you win the match. Using defensive items to build temporary armor can absorb damage in place of health points.
II. Backpack
In many other games, the backpack is used as a space to store items, or in some games, it functions as an interdimensional pocket that can hold an unlimited number of items. However, in this game, the backpack mechanism is more complex. At first, it might seem like you just need to plan out the backpack space, but it's much more than that. In this game, the focus is on how to combine different items to produce greater effects, which is what players need to "study" closely.

Let's talk about your own backpack. The backpack in the game serves two purposes: "storage" and "enhancing combat power." When you gain experience and level up, the ability bonus you receive is an increase in the capacity of the backpack, i.e., the number of slots. The initial backpack can theoretically expand to 11x5; the initial backpack space is the 3x3 grid in the center. Expanding the backpack also has conditions: new slots must be adjacent to existing ones, and as long as they do not exceed the blue area, they can be expanded in any direction. The higher the level, the fewer new slots you can obtain.

III. Items
Items can generally be divided into four categories: weapons, armor, accessories, and consumable items. The states of these items can also affect each other.
1. Weapons: Depending on their attack attributes, weapons can be divided into melee and ranged. Melee weapons are affected by the target's spikes, causing self-damage, while ranged weapons are not affected. Based on usage, there are disposable weapons that automatically break after a certain number of uses; limited-use weapons that can only be used a specific number of times per turn; stamina-consuming weapons that can be used as long as you have enough stamina; and magic weapons that generally require a magic crystal to be connected and consume magic.

2. Armor: There are two types, automatic and active. The former can release corresponding blocking effects each round, provided they are in the correct position; the latter requires stamina to use and can only enhance blocking when used actively.
3. Accessories: Accessories themselves cannot be used, but depending on their placement, they can enhance weapons, armor, and other items, sometimes even having negative effects on other items.

4. Consumables: After using these, you can obtain temporary status effects, such as restoring stamina, healing, or dealing damage. After use, the item will either disappear immediately or can be used multiple times, with consistent or changing effects. Different items have different shapes, and rotating them 90 degrees will change the direction if the item has a "directional" characteristic.

IV. Build Strategies
Build strategies are actually based on the direction of the items. Similar to other roguelike games, the variety of build strategies is vast, making each battle full of "chance." For example, stacking a large number of kitchen knives and using special kitchen knives to trigger each other can create a "Kitchen Knife Build" with mutual damage enhancement; equipping a vampiric weapon and a legendary rapier that significantly enhances damage after being hit can create a "Rapier Build"; placing nunchucks in the backpack and choosing accessories specifically for damage enhancement can create a "Bruce Lee Build." There are many build strategies, and you can gradually delve deeper into them.

This concludes the Backpack Hero beginner tutorial for now. This is a deep and creative new roguelike game with many interesting and novel designs that allow for extensive exploration and research of various items. Through the analysis above, I believe everyone can solve some of the basic issues during the early stages, allowing you to quickly integrate into the game.
