**Recommended — but with serious reservations.** Dimhaven has a strong atmosphere, an intriguing world and enough good ideas to make it worth playing, especially for fans of Quern and classic first-person puzzle adventures. I genuinely want to support developers who still make games like this. That said, the game often seems determined to make things harder in ways that are not particularly clever. First, I really dislike the pixelated visual style. I honestly do not understand why this artistic choice was made. The environments and atmosphere would benefit enormously from a cleaner image, but instead everything is covered by an artificial low-resolution effect that frequently makes the game uglier and harder to read. Several puzzles are also unnecessarily cumbersome or forced. Difficulty is fine; obscurity is not. Too often, the challenge comes from unclear visual communication, arbitrary ordering, or trying to understand what the designer expects rather than solving a satisfying logical problem. The Valaton Sequence near the end is the clearest example. The basic concept is not terrible, but the execution is frustrating: matching approximate values, understanding which number belongs where, and determining the intended order are all poorly communicated. It feels less like solving a puzzle and more like reverse-engineering the developer’s assumptions. So yes, I recommend it—but not without hesitation. There is a good game here, with real atmosphere and ambition, buried under some questionable visual choices and puzzle design that occasionally mistakes confusion for intelligence.
I have mixed feelings regarding Dimhaven. Overall, the experience was positive, but this game doesn't quite reach the superb level that the studio (Zadbox) demonstrated in Quern. First thing I must say is that the game does give a nice challenge: the puzzles are interesting, entertaining and not too frustrating (obviously, if a puzzle is not frustrating at all, then it's not as rewarding to solve it, haha). For those seeking my opinion, I would recommend buying this if you have enjoyed Myst-like games and Quern, but if you have a choice - try Quern and Myst first. Consequences of the short-notice release TL;DR: The game is nice, but way shorter than Quern and it is easy to notice that this was unplanned. Expectations vs. real game One thing to notice is that the trailer of the game was really promising. The idea and vibe were of the Myst-like games we all love. However, even the trailer showed several puzzles that didn't make their way into the released game! E.g. take a look at the clock puzzle at 0:15, photo puzzle and "LEAVE!" message at 0:19 or some sort of corridor at 0:35. Or take the amazing view from the beacon at 0:42. Or horror-like elements at 0:48. The trailer promised a lot of beautiful and neat things that I am fairly certain even worked, but were probably cut at short release window. There's a reason I blame the release timing: the game had numerous bugs right after publication. One of the funniest: look at the screenshot with a cat. It has a panel in the top: . Alas, map and notes were never available (I thought I failed to find some kind of journal, but it just ended up blocked until the very end), and a few days later a patch was released that removed these buttons altogether. The reason I write " had bugs " in italic is because most of these were fixed shortly! Overall, they didn't really affect my experience, but just gave a funny notion sometimes... But it made me think that a few times I was stuck were due to a bug. Story issues HEAVY SPOILER WARNING : this section may spoil your experience in your playthrough. Skip it if you don't want spoilers. Spoilers are unmarked. You have been warned. The story in Quern was rather deep. In my playthrough, it was that I slowly came to an understanding of the titanic work that was done by (Quern spoiler) the Professor in order to achieve his goal and (presumably) share the realm of Quern with the world . In Dimhaven, the story was more somewhat... I don't know, erratic? I'll explain what I mean in the next section. There are many areas in the game that seem to be explorable, but at some point you meet a one-way pass point without visiting. E.g., the protagonist comments on several locked doors that they are 'not gonna open without a key', yet you get no key at any point... Obvoiusly, it wasn't meant that way. Right after release, you used to receive a phone call with some spy-themed dialogue, but it turned out this line never got developed. The mere idea was amazing, because later you learn that in the realm of the game, a Secret Government exists, and this was such a promising move... But it ended up abandoned, as many other things. In the final game you only get a wordless call. Regarding the characters, first and foremost: the protagonist character is not introduced, and it is somewhat easy to skip the important story elements about who Zack is if you don't look in the album. The devs should have made a very short intro-game where you meet Zack (maybe in protagonist's childhood), communicate with him, receive some memento from him, or whatever. Other characters look similarly superficial and shallow. The hotel keeper explains nothing he says, and it basicaly soound like some gobbledygook. You can't even check into the hotel - that would have been a fun mechanic, if you ask me! The actions taken by the main friend/antagonist aren't explained either, and his decisions seem erratic and forced. For instance, why would he lie to the protagonist that he never knew Zack? Why does he neither help nor hinder the player? Why does he tell the crucial information in chunks? It never gets explained, even if you read the story carefully. The available answers of the protagonist also seem stretched and improvised, like in a bad play. Kalman Vosh also appears in an unexpected way and looks somewhat irrelevant to the story at first, while afterwards it appears that he was one of the central characters. Oscar Ravenstone is not duly introduced either. The worst part, though, is the ending sequence. When you "enter the sequence", the game unexpectedly... ends? And at the same time dumps the whole background to you which was not given earlier. Zack and Kalman Vosh turn out to be alive, Oscar disappears, while you don't really understand what exactly you have accomplished - instead, you feel as if you're a monkey that pushed some buttons. All in all, the story seems quite raw and underwhelming. It is not surprising, though, when so many gameplay elements got cut from the release - the story got severely damaged as well and the devs had to adjust somehow. Puzzles Spoilers here are marked . Most of the puzzles were good, in my opinion. Some of theme were even great! Yet, some of them seem to be made up on the spot and a little bit ugly. Where to start... Well, the beginning of the game was really well-made. The puzzles in the first area seem really well-thought. They are challenging enough, and while there is some space for improvement, this is a really decent work, better than many puzzle games. What I liked the most was the visa puzzle, which was quite complex but satisfactory. The next part ( link to the 'town' ) was ridiculously (and even insultingly) easy. In fact, (in my opinion) it is blatantly the worst part of the game. The terrain has invisible walls (which breaks an unspoken rule of good game-making), while the puzzle is as trivial and linear as it gets -- find a lantern and pass through a dark zone , really? Right after the release, this area was laggy as hell, and I had to switch from Ultra to Minimal settings to play further. The game even displayed a warning that I should switch graphics settings if I experience freezing. Luckily, the lags got fixed soon, but alas, the bad puzzle still persists. The hotel+turbine puzzles are also well-made. The best part was when you had to walk a large circle to get on top of the elevator - makes you think out of the box. The think that might possibly frustrate you (I think it is not a spoiler) is that you don't get the fifth level of power in this location - just don't try. The Raven's nest puzzles seem decent, but become overly linear, in my view. The Ravenstone lab safe puzzle, though, is exhaustive rather than fun (I still don't get how the cupboard drawers correspond to numbers , and I looked hard!). The final puzzle turned out to be too simple, in my opinion, and should have been done differently. However, it's not as bad as the game unexpectedly ending after this... Final verdict Well, having all that said, Dimhaven is still a decent game that I enjoyed. I recommend getting it, especially if there's a discount. However, I strongly recommend Quern over Dimhaven. Buy it, especially if you like complex puzzles and do not really care about the story.
The game starts out really strong, but the last 3rd of the game is kind of a letdown. The last few puzzles are a bit too easy and not that interesting. Additionally the ending to the story is rather abrupt and not all that interesting. Overall, the game wasn't bad, but it was definitely a step down from their previous work with Quern, which I felt was pretty close to being a masterpiece. With how the game ends, it looks like they are setting this up to be a series. Based on their previous work, I know they could do a lot better in a sequel.
The demo/the first hour of the game, is the best part of the whole game, and feels disconnected from the rest. Honestly the game only gets worse as it goes along, there are still cool puzzles here and there but its 50/50 in terms of quality. Quern was much better in how it handled exploration, puzzle design, and story. generous 7/10
