This article is about "Hero's Agent," a short RPG created using "WOLF RPG Editor."
I came across it on Freeware and was drawn to the game's atmosphere, so I decided to play it.
Although it was a short game, the atmosphere within the game was impressive and left a lasting impression.
The completion time is just under an hour.
Game Overview

Fifty years after the world was ruled by the Demon King, when people had given up hope, a hero rose up.
The hero somehow managed to reach the village at the foot of the Demon King's castle, but he ran out of strength there.
Three young men living in the village, out of respect for the hero who had reached this far alone, decide to challenge the Demon King's castle in his place, so that at least the story of "challenging the Demon King and falling in battle" can be told.

The movement screen in this game looks similar to that of 3D dungeon RPGs such as "Wizardry".
There's no mapping function, but the dungeon isn't very big, so you probably won't get lost.
You progress by collecting treasure chests and disarming puzzles as you go.

As you move around the dungeon, regular battles will occur randomly.
The battles are conducted using a standard turn-based command battle system.
SP is required to use techniques.
Since normal attacks are not very effective, it will be important to actively use special techniques.

Up to this point, it looks like a typical RPG with a standard system.
However, what makes this game unique is that it doesn't have the concept of upper limits on "maximum HP" or "maximum SP."
In other words, if you use healing magic, your HP will keep increasing, and if you use SP recovery items, it will increase without limit, just like HP.
Due to these inflationary features, the difficulty of completing the game isn't that high once you get the hang of it.
Review (no spoilers)
I was able to clear it in less than an hour.
The atmosphere of the prologue and epilogue, in particular, evoked such a profound feeling that I wanted to write this review.

The hero who set out alone to save the world and perished unnoticed was reminiscent of Ortega from Dragon Quest III, and it left me with a melancholic feeling.
The situation of challenging the Demon King's castle with a desperate resolve, all for the sake of the hero's honor, is truly thrilling.
The fact that the three of them had a lighthearted rather than a serious demeanor made the impression on me all the more striking.
I encourage you to play the game and find out what kind of ending it has.
The difficulty level of the game itself is not very high.
Those unfamiliar with 3D dungeons might be confused, but the dungeon structure isn't that complicated.
As for combat, there are loopholes that allow you to earn money, so you shouldn't get stuck.
Conversely, it's a game that can be played casually in a short amount of time.
If you're even slightly interested in the atmosphere from screenshots or other images, why not give it a try?
Strategy Notes
I don't think this game requires a walkthrough, but I'll include a few notes anyway.
With the Ring of Life, which automatically restores 5% of HP each turn, and the Ring of Spirit, which automatically restores 5% of SP, you can raise everyone's stats to the maximum by persevering through battles.
For example, if you equip Adonis with the Ring of Life after raising his HP to a certain level and have him continuously defend using the "Stand Firm" stance, his HP will increase exponentially, much like a debt growing with compound interest.
(1000 → 1050 → 1102 → 1157 → 1214...)
The same applies to SP; it can be increased indefinitely by continuously defending during battle.
In reality, you can defeat the final boss without raising your stats that high.
It's fun to watch them increase, so it's fine to raise them until you're satisfied.

A compilation of gaming-related articles featured on this blog.
The download page for this game supposedly describes its concept as "loose resource management," where "using special abilities too much will deplete your SP, but not using them will leave you with insufficient HP, and avoiding battles altogether will prevent you from obtaining enhancement items, but it's not so strict that you need to calculate everything meticulously." But isn't that a bit too lenient?
Thank you for your comment.
Admittedly, since there are accessories that restore HP and SP every turn, I felt that the resources were practically unlimited and the game was too easy.
However, without this accessory, I think it would require a certain level of resource management to achieve the right balance.
In my case, I was more drawn to the prologue and epilogue than the gameplay itself.
Those who are looking to achieve a balanced gameplay experience can add restrictions, such as prohibiting the use of accessories.
