Gra na początku sie robi ciekawa, potem w połowie nudna, ale pod koniec na całokształ sie super i fajnie mi sie w nią grało polecam
Pros: - I liked the characters. - I liked the style choices. - I liked the sense of adventure. Cons: - Many of the puzzles are awful. Some of them are incredibly simplistic, others require ridiculous leaps of logic, and it felt like there was little in between. - Some of the mind maps are incredibly unintuitive. Sometimes you have to draw genuine connections, other times you have to draw connections you *know* to be wrong. And there's often multiple nodes referencing the same idea/concept/object, so it becomes a guess to know which one to choose. - Some puzzles require you to go back and look at items you've already looked at, even though you (the player) already know exactly what they contain, and so should your character. This forces you to go back and revisit things that you should rightfully think you're done with. - If you miss something said in a dialogue, there's no way to replay that information without replaying the entire chapter. - Some of the dialogue is slow and unskippable. - Many times, a dialogue choice was obvious to me, but the game would gatekeep it behind needing to walk across the map to click on something (so that my character could make an observation I'd already made) before coming back again. It felt like filler, and didn't make me feel like my time was being respected. - The game crashed multiple times for me.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

A wonderful little detective game where you wind up playing all sides of the story to a rather inevitable conclusion, with a cute little framing device. Definitely a fun adaptation of the character. The gameplay is nothing new, but its well-done, even if occasionally steps can be a bit opaque.
J'ai passé de très bons moments avec ce jeu, qui permet d'explorer des environnements variés (bateau, égouts, plusieurs beaux manoirs) et d'entrevoir Arsène Lupin dans un jeu vidéo. J'ai plusieurs conseils à vous donner pour passer un bon moment et éviter quelques crises de nerfs : 1. Je conseille de lire d'abord le livre Arsène Lupin, gentleman cambrioleur pour bien comprendre les personnages et les intrigues, parce que ce jeu est l'adaptation de ce livre. Tous les personnages du jeu se trouvent dans le livre et il est très intéressant d'imaginer d'abord soi-même les scènes avant de les voir en adaptation. Le système de jeu est du genre "point and click" : on clique pour avancer, dialoguer et observer des objets. J'ai été plusieurs fois bloqué par une mécanique énervante : des codes à 4 chiffres. Parfois le code est évident, mais parfois il est tiré par les cheveux. 2e conseil : il faut donc jouer avec un papier et un crayon à côté de la manette ! Quelle est la date de naissance de Lupin ? Quelle est la date de naissance du duc Rollon ? Combien de côté ont plusieurs figures géométriques : carré, cercle, triangle, hexagone ? (exactement dans cet ordre !) Je regrette aussi qu'on ne puisse pas prendre tous les objets dès le début du niveau pour les utiliser ensuite au bon endroit. Cela aurait ajouté du plaisir. Prendre la marmite, la flûte, le beurre, la levure, le tuyau, pour ensuite comprendre à quoi tout cela sert : réaliser un produit pour révéler quelles tableaux du baron Cahorn sont authentiques ! (en fait la flûte sert à autre chose, mais la flûte m'a posé problème parce qu'elle est apparue dans une caisse que j'avais observée plusieurs fois avant sans rien y trouver) 3e conseil : aller voir une solution pour éviter de rester bloqué plus de 5 minutes sur le même problème. En bref, j'ai aimé : - les graphismes - les mécaniques simples (déguisement, codes évidents) - retrouver Lupin, Cahorn, Ganimard, Nelly, les personnages du livre Gentleman cambrioleur Je n'ai pas aimé : - les trop nombreux codes à 4 chiffres ou énigmes - de devoir suivre objet par objet les intrigues dans un seul ordre - les cartes mentales qui ne révèlent rien parce qu'on a déjà compris, mais qui sont obligatoires pour avancer
日GN-2/10分 玩了两章,体感不好,可能之后很闲才会考虑继续玩完。 谜题简单只给,但是翻译不行,里面居然有选项是男的说自己是独生女,而且问题下面的注意事项小字翻译也是不知所云,误导性极大。 玩法又简单又卡手,主要是操作手感不好。游戏推荐手柄游玩,但实际游玩的时候,用摇杆找线索准星移动得极其之慢,不如用鼠标。视角转换也难受,不如不要固定转90度,直接自由转角度找线索,都会舒服很多。 而且在场景多的时候没有传送点,哪怕只有几个也好,而不是来回跑很远,纯浪费时间。 以及有一些bug更是影响体验,比如UI上的bug,鼠标悬浮状态同时出现好几个之类的。UI交互和美观度都很欠缺。 总体而言不推荐,请勿浪费钱。
A fun and interesting point-and-click adventure game, but pretty short, around 7 hours play time. The puzzles are not too difficult, but the objects sometimes are quite difficult to find. Recommend to buy only when there is a discount. (I bought it with 75% off discount)
Probably the best isometric detective game from the studio: Lupin is a much livelier hero than the tedious Poirot. Cohesive, atmospheric, true to the spirit of the original, with a great soundtrack and those signature mind maps that, as always, seem to make sense only to the developers
Aaaah Euhhh Ooohh Oui j'ai détesté : ce jeu n'a aucun intéret :un ennui mortel ....
not that great, but also not that awful the thing i REALLY liked was the story being accurate to "arsène lupin, gentleman thief" (but with some changes, of course), i think they did a great job in adapting it into a game! but other than the story i feel like the game is a bit lacking... ≈8 hours is too short for a game that costs 30 dollars. (and even IF it was longer it would be way too repetitive because the game ALREADY IS repetitive!) both gameplay and controls could be better, especially the gameplay because it gets really annoying to walk around all the map for 2 or 3 times looking for a clue, just for the "clue" to be a random unrelated observation on a item you already clicked twice buuuut because you didn't click on another item before clicking on it, arsène "the smartest guy on the room" lupin doesn't say the ♥♥♥♥♥♥♥ thing i needed him to say 20mins ago. i recommend it if you are either an arsène lupin fan (like me!), or if you just want to try a game that isn't too time consuming (also like me!), but remember to buy it on sale
Un jeu de détective vraiment sympa à faire, les graphismes sont joli on est plonger dans cette histoire je recommande vraiment
