Case-study: Integrating Bench Universal Save System into Kailius

Originally developed for Terresquall’s Metroidvania tutorial series, the Bench Universal Save System provides a flexible way to manage save files, persistent data, and multiple save slots. We will use it to add an in-game save bench and integrate Bench’s built-in save slot menu, allowing players to start and load different save files.

In this article, we will cover how you will go about implementing the Bench Save System into your game by implementing it into an existing open-source Unity 2D platformer called Kailius.

GitHub Desktop for Unity — Part 4: Branching

Using GitHub Desktop for Unity collaboration

In the 4^th part of this series, we dive into one of Git’s most powerful features—branching.

When working on projects, it’s common to accidentally overwrite someone else’s work or struggle with testing new ideas without affecting the main project. Branches act as a safe workspace, letting you build new features without worrying about breaking your existing game build.

In this article, we’ll explore what branches are, how to create and manage them, and how you can use them for your own development workflow.

Creating a Rogue-like (like Vampire Survivors) in Unity — Part 28: Persistent Power Ups

This article is a part of the series:
Creating a Rogue-like Shoot 'Em Up (like Vampire Survivors) in Unity

Update 10 April 2026: There was a small error with the GetFeeCost() function in PowerUpData as it did not use the feeFactor set. It has been fixed.

In this part of the series, we will be implementing a more robust save system than the one we had in the previous part. As we have recently created a robust save system asset called the Bench Universal Save System for the latest part of our Metroidvania series, we are going to upgrade our save system to use it (and make the development of our save system much easier).

On top of that, to test out the save system, we are also going to implement the power-up screen into our project as well, so that players will be able to buy something with the coins they have collected.

Creating a Metroidvania (like Hollow Knight) in Unity

In Part 15 of our tutorial series, we will be working on implementing a new and improved save system that supports multiple slots for our game. This new save system will be more robust and less buggy than our old implementation, which used the deprecated (and less flexible) BinaryWriter class in C#, and had a multitude of problems as a result.

Creating a Rogue-like (like Vampire Survivors) in Unity — Part 27: Treasure Chest UI Animation

Creating a Rogue-like Shoot 'Em Up (like Vampire Survivors) in Unity

💡 Update 7 November 2025: Some bugs were found with the content for this part by our Patron Grim Rubbish. These bug fixes are addressed in this post here.

Now that we've set up a coin collection system from the previous part, we're now ready to improve upon the very simple treasure chest that we've implemented in Part 12 to faciliate weapon evolution. In this part, we’ll enhance the treasure chest system to more closely mirror the mechanics seen in Vampire Survivors.

Our upgrades will include the ability for chests to level up existing weapons and passives, grant entirely new ones, and reward players with multiple items at once—ranging from 1, 3, or even 5 rewards per chest.

In Part 14, we are going to be improving upon the pickup system, and the UI overlay that pops up when you pick up an item. We are also going to be using the hit stop system that we made in Part 11 for the UI interlude that happens whenever we pick up an item.
