Great follow up to Tangle Tower. The game feels quite a bit meatier than the previous game too, but that's possibly just because I'm taking my time. Either way, I don't think fans of the previous two Grimoire games will have anything to complain about here. Puzzles could have been a bit trickier, but the actual story had a number of surprising turns I did not see coming, which to me is a sign of a good mystery, especially because it all feels quite satisfying in the end. My only real complaint is that the game ends at some point and I can't have more of Sally's and Grimoires banter :(
Utterly fantastic. Probably the best Detective Grimoire game yet Well written, consistently funny All the characters are unique and fleshed out with great voice acting across the board Most of the puzzles are completely original and fun with like 1 that i didnt really enjoy(typewriter puzzle) but most were fun to solve The setting, music, art, animations, for the characters are really well done and really immerse you in the game The core mystery is fun to solve and all the characters involvement in said mystery Get this if you like detective/puzzle games it is well worth your time Edit: getting all the achievements isn't TOO terrible, most of them you will get by just interacting with everything, but there are a couple MISSABLES so I would definitely look those up when you play this game, so you don't miss them and have to replay the entire game again. theres like 3 to look for and are not hard to achieve you just have to know when they are.
💎INDIE GEM BADGE💎 Having played the first two games on Steam and enjoyed them a lot (also the original Flash game back in the day), I find this game exceeds them. Detective Grimoire is back with another case to solve. He received a letter about the murder of Captain Magnus Mortuga in his own submarine. He and his partner Sally arrived at the seemingly abandoned fishing town, waiting for their contact, having stayed all night in the wretched down inn. Grimoire decided to search the town, only to find the submarine where the murder had occurred. Hopping in, they started searching the rooms, interviewing the suspects, and gathering all the information needed about their victim. https://steamcommunity.com/sharedfiles/filedetails/?id=3767458160 The story is extremely well written; the dialogue, the characters' interactions, and the way things unfolded were out of this world. The gameplay is like the previous one; you roam around the submarine, checking rooms, interacting with almost everything, checking all items and collecting them as evidence, which you can later use to ask the suspects about them. You don't have to keep notes aside to remember everything. The developer has kept everything organised, and you can access everything you've discussed with the suspects under each item, including what they said about each other. It does make the deduction section easy at times; however, I found a couple of them challenging. The puzzles are fun and different from the common ones, and while there is no skip option, none of them was frustrating. If you fail to solve them, the characters will give you a hint on how to solve them. https://steamcommunity.com/sharedfiles/filedetails/?id=3767458127 The voice acting is top-notch! They captured each character's personality perfectly, making them all likeable. I didn't dislike any of them, and when I learned in the credits that one voice actor played two totally different characters, it made me appreciate their work so much more. The soundtracks are outstanding. I do wish we had an option to download them; they were so good, and each character theme is fitting! The artwork is immaculate; the character design, room details, and animations are phenomenal! I even loved the concept art they provided after you finished the game, and the artist's insight made my heart swell. Just like in the previous game, I appreciated the time and love everyone poured into this game. https://steamcommunity.com/sharedfiles/filedetails/?id=3767012211 Pros: +Immaculate artwork and locations. +Well-written murder mystery story. +Interesting characters and perfectly captured their different personality. +Fun and great soundtracks. +Useful notes and list of items to help you with your investigation. +Original puzzles. +Great animation and character design. +Fast travel map. +Mystery/detective style. +Outstanding voice-over. Cons: -You can't skip puzzles. I can't recommend this game enough; it ticks the boxes in every aspect. I wish there were more games like this, and I can't wait for a new Detective Grimoire adventure.
