## What is OnceWorld?

OnceWorld is a simple and casual 2D solo-play RPG.
Relive the charm of classic MMOs from the good old days — now reimagined for mobile with easy controls and deep progression!
Level up, reincarnate, raise pets, awaken equipment, collect materials, and battle in the arena — all in one nostalgic adventure.

It’s an RPG that brings the essence of those mid-2000s MMORPGs to your smartphone, blending nostalgia with modern convenience.

▼ Stat Distribution

Distribute points into seven basic stats to develop your character.
Points are earned as your hero levels up.
To reset your distribution, you’ll need a special item.

Stat meanings:

VIT – Increases HP

SPD – Attack speed & number of strikes

ATK – Physical attack power

INT – Magic attack power & SP capacity

DEF – Mainly physical defense power

M.DEF – Mainly magical defense power

LUK – Evasion & Physical Critical

▼ Weapons & Armor

Equip one weapon and five armor pieces.
Wearing all five pieces of a matching set grants a set bonus.
Use the heart icon at the top-left to toggle your favorite gear display.

▼ Equipment Enhancement

Use materials obtained during your adventures to enhance your gear.
Each enhancement attempt has a success rate — failure consumes the materials, but the item itself will never break.
Some special items can increase success rates.

▼ Accessories

Accessories grant special effects when equipped.
Defeating enemies while an accessory is equipped will level it up, enhancing its effects over time.

▼ Magic

Spend SP to cast powerful spells.
Magic attacks cannot be evaded and there are no critical hits.

Certain rare materials may further amplify spell power.



▼ Monsters & Pets

By carrying a special material, you’ll gain the ability to capture monsters.
Captured monsters become pets that grow stronger as they fight alongside you.
Some monsters learn skills as they level up.
These skills can activate even without being summoned, as long as the monster is accompanying you.

Pet switching can only be done at the Pet Keeper in your hometown.
Feeding specific materials will raise a pet’s stats.

▼ Monster Encyclopedia

Once defeated, monsters are added to the encyclopedia where their stats can be viewed.
Captured monsters will display a “Caught” mark.

▼ Materials

Materials are divided into three categories:

Normal Materials
　Used for equipment enhancement and trading.

Effect Materials
　Provide passive bonuses simply by owning them.
　Have a smaller carrying limit.

Key Items
　Only one can be held.
　Cannot be dropped or sold.

▼ Items

Items that grant various benefits during adventures.
You can assign them to shortcut slots for quick use in the field.
Swap registered items using the arrow icon beside the item list.

▼ Reincarnation

When your hero reaches the level cap, you can reincarnate.
Reincarnation resets your level but increases your level cap and available stat points, allowing for further growth.

▼ Abyss Corridor

A ranked mode that can be played a limited number of times per day.
Clear each floor by defeating all monsters as fast as possible — faster times rank higher.
Treasure chests appear as rewards on each floor.
Only Save Slot 1 is eligible for ranking participation.

▼ Arena

Watch monster battles.
Watch monster battles held several times a day.
Choose the strongest team from three teams and watch the battle.

Earn Arena Coins if your favorite team wins.
Try exchanging them for valuable materials at the Arena Shop.

▼ About the Kin-Slayer Rite ▼

The Kin-Slayer Rite
is a ceremony in which the target pet’s kin-bond, level,
and accumulated experience are all returned to zero
in exchange for enhancing its base stats.

A monster that undergoes this rite will gain experience
at a slower rate thereafter.

### 3/5 — 面白いのだけど…

*2026-08-03*

素材を集めに面白さがあるのかと思いきや、レベルの代わりに素材集め(レア:立方体とかルミナス等含む)がある感じ。

レベルはあるようでない。輪廻もいいんだけど、もはやありがたみがないから、それならレベル1000になった、2000になったみたいな達成感がほしい。

MMOって
レベリング+金策のバランスがよい狩場を探して強くなって、ドロ出たら美味いみたいな感じよね。
レアドロ狙うならレベリングと金策はちょっとお休みみたいな。

レアドロ1000個集めないと先に進めないの縛りが本当にめんどい。
それやってるときに成長する要素が一個もないから。

起源も全部課金してるけど、とにかく飽きが早い。

ステ振りにも色がないし、ドロも出て嬉しいじゃなくて持ってないと進めないだから。
ガチ勢はアプデ待ち、中堅は緩和待ちになってるのでは？

待ってる間もキャラクター強くさせてもらえる要素が欲しいです。

### 2/5 — 軽く楽しむぐらいなら

*2026-07-23*

ペットにスキルが増えたり、アクセサリーが増えたり、前作とは違った面白さが追加されている。どうしても寝放置などが必要になるが、それは前作も同じだったのでそういうゲームだと納得している。が、デフォルトの状態で放置していると敵のリポップが遅くなり、改善するには課金するしかない、と前作と比べて明らかに課金への誘導が行われている。課金を促すのはいいのだが、今まで出来ていたことを出来なくしてそれを行わないで欲しかった。この要素だけに3000払うなら他のゲームやる。するのなら課金すると2倍で湧くとか、下げるのではなく上げる方向にして欲しかった。また、現在借金返済のメインイベント中なのだが、100億は桁がおかしい。10億、最低でも50億ならばまだ現実的だった。循環宇宙回り続けることが本当に苦痛。金策緩和の敵を、シナリオで使える進行度で出して欲しかった。装備の強化もゴールドでできるようになったが、返済するまではその要素に触れる余裕なんてない。ボスを放置で倒すことも考えられるが、アナトユを放置で倒すのは煉獄ではほぼ無理で、ゴールド強化のおかげで今後使わないであろうドラゴン装備をこのためだけに育てなければならない。こちらも2〜3000課金すれば一瞬で終わるなど、課金誘導が酷い。課金要素が多くても最悪構わないから、単価を下げて欲しい
総評として、寝放置などが大丈夫な人が軽く楽しむ、ぐらいなら(それでもかなり時間はかかるがまだやりがいがあるレベルに収まる)良いと思うが、ちゃんとやるなら課金をするか、手動10時間以上同じ作業を行うなどの地獄を行う覚悟が必要

### 3/5 — Ugh

*2026-07-14*

I was enjoying the game. Purchased stuff, but training grounds I assumed were for training….. I died TRAINING , lost 2 million dollars. Now I don’t even want to play :( please have something that informs about having to rebirth when reached level 100, and you can still actually die in training grounds. I’m legit so upset because I spent real money just to lose it thinking training grounds was just training.

### 3/5 — 課金出来るなら良ゲー、課金出来ないならプレイ非推奨

*2026-07-06*

【要約】
・面白いけど無課金だと相当キツい


【良い点】
・運に左右される要素が少なく、やり込めばやり込む程順当に強くなれる
・アプデの頻度が高く、基本的にやる事が尽きない
・敵をペットにするシステム&ペットスキルで主人公強化と言うシステムが新鮮で楽しい

【悪い点】
・大体のアプデがトップ層向けのもので、それ以外の人々は既存のステージをひたすら周回する事になる場合がほとんど
・課金アイテム(1つ3000円弱)が強過ぎる上に、それ前提の素材要求量
・アプリを開いたまま放置する時間が長く、端末への負荷が大きい
・無,微課金だとゲームの進行が非常に遅くなる


【総評】
○ゲームシステムはとても面白い

○無課金でプレイするのはおすすめしない
・そこそこで楽しみたいなら一通り緩和されるのを待ってから始めるのがベスト
・高難易度のゲームを楽しみたいならアリ

○6,000円程なら払っても良いかなと言う人にはおすすめ出来る


【個人的な感想】
今作はリエンド+αと言う印象。
序盤のペットが活躍出来ない問題や、防御系ステータスが実質機能していなかった問題が上手く解決されていてとても嬉しい。ペットスキルやアクセサリーによって戦略がより幅広くなったのも良い点。
無,微課金ユーザーに厳しすぎるのと、必要な放置時間が長すぎるのが問題。

長文失礼しました。

### 5/5 — Five star all the way

*2026-06-29*

I absolutely love these games. I’ve been waiting for another one to come out since finished Re:END. This is absolutely another banger 
The only thing I’d like to see added is to be able to move your items that you put on screen they’re in the right bottom hand corner. I love be able to move them to the left because I’m hitting them all the time. Other than that, keep up the good work.

### 5/5 — Love it

*2026-06-24*

Like it’s precursor a true gem to be enjoyed for hours and hours

### 5/5 — Absolutely love but needs a English Wiki

*2026-06-19*

This type of rpg game is one of my favorites, I love having to grind up on so many things and then reset back like this but I feel like you can hit power walls often and I am not entirely sure what to do. I played ReEnd which is very similar to this and I learned on my own on how to break those power walls you hit but with this I have gotten lost a few times and don’t know the best way to get stronger. I enjoy having to learn things on my own but sometimes it is nice to have a guide of some sort for things and for the English players like myself there isn’t enough for us on your Wiki/Discord to get stronger when we are stuck. If you can add more help for the English players that would be amazing🙏

### 1/5 — 最低なゲームです。ガチでやらないでください。

*2026-06-12*

私はこのアプリが売り出す買い切りのアイテムを全て買って長らくこのゲームをやりまひたが新規の方はいっさいのプレイをおすすめしません。貴女がどれだけ金持ちで無限の資金をこのゲームに費やしたとしても初心者や中級者の救済などこのゲームの作者は考えておりません。一部の上級者から搾り取れればいいという考えのみで運営されているゲームです。今から始めて金払えば追いつけるなんて甘い考えはやめてください。大量の金を払ってハムスターみたいに回し車を回し続けて、なおかつ手動でゴミみたいな時間をついやしてやっと貴方は過去からずっとやってきた方々に並べます。時間が無限にあって本当に暇な人間にのみおすすめのゲームです。

### 5/5 — Amazing

*2026-06-04*

Fantastic content, well made for player enjoyment, not a money grab, and flat out an instant favorite

### 5/5 — 快適性に10000円？はぁ？

*2026-05-24*

リポップ遅延削除、アリーナ報酬2倍、経験値2倍に各200クリスタル、計600クリスタル。

300クリスタルが4800円。

この感じだと今後も利便性を上げるアイテム全般が課金アイテムとして配布されそうな予感がします。

それも今回同様に馬鹿らしい値段設定で。

課金大前提の廃周回無限インフレ単調放置ゲームとかソシャゲよりタチ悪い。

この制作者は時間とお金の大切さを伝えるのが本当に上手い。

それはそうと廃人なのでもちろん全部買います。

パチンコで3万擦ったと思えば安いもんです。

それどころか本来の損失3万円を1万円に抑えられたわけで、実質2万円得しています。

有難うございます。

追記: おかげさまでトータル10万円ぐらい浮きました。

記念に引退します。
