### 5/5 — PLS RUSSIAN LANGUAGE

*2026-04-01*

Great game. I’m really looking forward to the translation into Russian🔥❤️

**Developer response:** Thank you for playing!
It might be difficult to add more languages, but I’ll think about it!

### 5/5 — とても面白い

*2026-02-02*

遺跡ステージのクリアまでプレイしました。楽しいゲームをありがとうございました。
以下ネタバレ含む感想です。

序盤：地道に掘っていき、新しい鉱石を見つけてドリルを強化するのが楽しい。

中盤：ワープ機能の解放によって効率アップ。ドリルの効果を色々試して強化し、より快適&爽快な穴掘りへ。
999層到達。

終盤：遺跡ステージ。呪いでブロックの耐久力が数百倍になることも。
「歯車集めるの大変だな」
→「爆破で壊そう」
→「『爆発強化』って重複すんのかな？」
→「『爆発強化＋＋』✖️3作ったけど変わんなくね？あ、ドリル変えてなかった」
→『ボンッ』「え、やば」
マップに大穴開いてちょっと引きました。遺跡ステージでは諸刃の剣なので使うときは注意。

**Developer response:** たくさん遊んでいただきありがとうございます！

### 5/5 — 神ゲー

*2026-01-19*

参考にしてもらえればうれしいです（楽したい気持ち強めのお気持ちコメントばかりです）

途中からネタバレ注意

・設計図作成の簡略化をお願いします、数百個作ると時間かかりすぎます
（例えば鉱石を使う倍率を上げて、1倍で15鉱石使って1個入手5倍で75鉱石使って5個入手みたいなことをしてもらえると楽になると思います。）
・ドリル製作時のやり直しが昔に比べると良くなってると思いますがもうちょっと簡略化してもらえると助かります、数百回以上やり直しするのが苦痛に感じてしまう
（例えば能力一覧を表示して、〇〇の能力が出るとやり直しみたいにすれば楽になると思います。）
・999階層に到達時のリザルト画面を早送りで出すかスキップする事が出来るように設定で変更出来るようにすると周回が捗ります。
・最終的に自分の思う最強ビルドが決まるのは良いと思いますが正直言って収集家特化のドリルと収納上手と幸運特化のドリルが最強すぎて他の能力が数十倍弱く感じてしまって使う気になれません、なので他の能力の強化や変更等をすれば自分の思う最強のドリルを見つける楽しさが出ると思います。
・遺跡のレベルをもっと上げて欲しいです。20レベルまでとは言わずに無限に進めるステージを用意してもいいと思います。

ここまで見てくれてありがとうございました。是非参考してもらえると嬉しいです。このゲーム本当に大好きです。

**Developer response:** 遊んでいただきありがとうございます！
設計図やドリル制作、ステージ周回等の遊びやすさについては、今後も改善していく予定です。
また新コンテンツとして、新たなプレイヤー強化手段を準備中です。
現在使いづらい特殊能力についても、うまく組み合わせて使えるようにしたいと考えています。
お楽しみにお待ちいただけるとうれしいです！

### 5/5 — ゲームが苦手でも楽しめる！

*2025-10-01*

中毒性抜群な作業ゲーで、一度やり出すと時間を忘れて没頭してしまう良ゲーだと思います。SEがとても良くASMRを聴いてるような癒し要素もあるゲームです。遊ぶ際にはイヤホンやヘッドホンを付けると、より魅力を感じられるのではないかと思います。

ゲームシステムがシンプルなのも良く、ただ下に掘るだけ！それだけなのだが、特殊な効果をもつスキルのようなシステムがあり、組み合わせも豊富なため、ビルドを考えるのもとても奥が深くて楽しい。ドリル作成などで行うパズル要素も脳トレ感覚で楽しめて非常に良いアクセントになってると感じました。

残念な所をあげるなら、ドリル作成に関して狙った能力を"全てピンポイントで"付けたいとなると、再抽選を何度も繰り返す事になります。後半に登場するアクセサリーのシステムも、狙いたい能力を付ける場合かなりの運ゲーなため、そこが面倒なポイントだと思いました。

**Developer response:** 遊んでいただきありがとうございます！
ドリル作成については、特定の能力を狙うのが少し大変すぎるかなぁと考えています。
今後のアップデートで、再抽選の高速化などの若干の調整を加える予定です。

### 5/5 — Game play

*2025-07-17*

Love the game. Wish there were more out there like this. Lots of great features. Great job.

**Developer response:** Thank you!

### 5/5 — Masterpiece

*2025-07-06, version 2.2.0*

Similar motherlode flash game very fun

### 5/5 — 面白かったです。

*2025-06-26*

かなりやり込みましたが、新要素も追加されて楽しめるゲームでした。爆発強化が強すぎるので、後半それしか使わなかったです。
爆発の威力はドリルダメージの会心3倍ダメージくらいで範囲に与える方が良かったと思いました。
あとエンドレスモードでどこまで深い階層を目指せるかとかのモードがあったら楽しいなと思いました。
鉱石の木も100レベ以降ものすごい必要鉱石量が必要だけど微量で効果が上がったほうがもっとやる気が出ます。

色々書きましたが、本当にハマるゲームです。ありがとうございます。

**Developer response:** 遊んでいただきありがとうございます！
いろいろな特殊効果を楽しめるよう、爆発強化くらい派手な効果を他の能力でも体験できるようにしたいなぁと考えています。
明かり範囲によって大きくなるブラックホールを生み出す、みたいな必殺技システムを検討中です！

### 5/5 — とにかく楽しいし面白い

*2025-06-15*

このゲームが面白すぎて初レビューです
ローグライク系が好きな人ハマるかも
ゲームバランスもちょうどよく、後半からできることが増えてどんどん楽しくなる！

私の進行度は中盤ぐらいまでですが、設計図作成解放&ドリル四つ装備可能、になるぐらいまで遊んだらそこからさらにどハマりしてしまいました
石と鉱石を下に向かって掘るという単純なゲーム性なのに、楽しくさせるアイデアと工夫がとにかくたくさんあるし、全体のバランスも良く調整されててすごく遊びやすい！
出会えたことに感謝するレベルで面白い🌸
広告の頻度もすごく低くて、もはや作っている方にもう少し還元したくなるくらい

**Developer response:** 初レビューありがとうございます！
これからもほりほりドリルを楽しんでいただけるとうれしいです！

### 5/5 — Very fun (v2.2.0)

*2025-06-14*

In most other inventory games, the moment you're full, you're forced to leave anything else behind.
The way the dev balanced it here while letting me bring every loot back is marvelous.

I had really thought it was a generic digger I'd played before, until I saw the puzzle parts.

With v2.2.0, I bought to disable ads. 
Try it, play offline, and buy to stop ads if you like it. It's a fantastic game for mobile after that.

Previous review pre v2.2.0: Ads are inevitable huh
I did not mind viewing one to reroll a drill, but forcing one right at teleporting back up with that anticipation to make drills, ruins the flow a lot.
Also, every single ad is porn which is why ads suck

**Developer response:** Thank you for playing!
(Update) Sorry for the inconvenience.
I didn't intend for those kinds of ads to appear, and I'll be reviewing the settings.

### 5/5 — Perfect at what it does

*2025-06-11*

This is a fun digging/mining game that scratches the incremental-progress itch that we’re often looking for in phone games. 

It doesn’t really have any peril like its inspirations(?)/predecessors (that I loved) like [Edit: spelling the game name right - how embarrassing] Motherload or Steam World Dig. That would be worse for a pc/console game, but it’s perfect for mobile (and younger players). 

The ads aren’t terribly intrusive, but I’m glad that a recent update just added an IAP to disable them. That makes me feel much better letting my kids play. Also, it’s just a good game; the dev should feel good about charging for it (even if $3 is a pittance and modern game pricing is just bewildering).

Last, I just want mention how much I love how the game keeps adding little systems and upgrades well past what you would normally expect. It’s just very cleverly done. Once I finish writing this, l need to go see if the dev has released anything else. 

This game easily earns a 5/5 and a Touch Arcade (RIP) comment-section ascii cat. <3

**Developer response:** Thank you so much for playing!
I also love Motherload, and this game was heavily inspired by it.
(I removed the action elements to make it more cozy to play.)
I'll keep making laid-back grinding games like this one in the future!
