Overall enjoyable game with very unique battle system. The roguelike elements were a bit weak. I played only on the hard difficulty (no magnetism modifier) and was able to get to the true ending without dying once (the enemies on true ending path were actually pretty hard though). I wasn't forced to really build around what I found. I just forced the same build every time using gold swords and stacking attack and defense as needed. The merchant bartering system is too easy to abuse. A very simple strategy I used was to take the 60 currency instead of a relic from the first dangerous battle, then max out the wandering merchant's rapport by overpaying for cheap items 4-5 times. At this point you can literally use his stock to barter for his other items at a huge discount and make infinite value worth of items which you can use for him later and also for every other merchant. The story was interesting but not extraordinary.

What started as a simple and easy roguelike quickly turned into a complex and deeply intriguing game and story. When I got to the end... i wasn't expecting to want to get to the next end. and the next one... and the next one. If you like unique combat, this'll be a treasure. If you like roguelikes, you'll enjoy this one If you like crazy stories with steins gate vibes, you'll love this one.

Overall a wonderful game with an amazing experience to dive into. Gameplay 9/10 Very friendly gameplay with its unique time-stop mechanic that doesn't require quick reflexes despite being in a bullet-hell situation. The weapon crafting system is well-thought with its QOL settings and some blueprints with different functions that will help fight or defend against enemies later on. The difficulty is certainly managable but there are some difficulty spikes that may come to a surprise in some cases. Story 7.5/10 The buildup at the beginning may lead to more curiosities as you dive deeper into the depths. Almost all the dialogues or text are easily digestable making it easy to understand the situation. However, while you are often left with more answers, there are some parts of the story that felt missing or disconnected from one and another, most of the time not because the dialogues are confusing or hard to understand but rather there are no explanation at all in most cases or few things that cannot make sense which can be pretty annoying to think about. Nevertheless, i still love the story with the setting of Moma's dive into million depth discovering and learning about the world underground in a way we can understand while witnessing the influence/consequences of our actions. Soundtrack 10/10 I really love the soundtrack that plays in almost every scene. The background music that plays in different scenes are very fitting whether its during a battle, crucial discovery, atmosphere, and many more. The variety also helps keeping the experience fresh. Illustration 9/10 I have to say, Moma is pretty cute ! In my opinion, the illustrations are quite pretty describing current events and more. Most of the illustrations are for aesthetic purposes which is a nice breath of fresh air once in a while. If only there is a way to disable/hide UI's to take a screenshot though.

Spoiler-free, rather messy collection of thoughts about Million Depth: 🟢 The most unique gameplay mechanic in recent memory. I always search for games with new gameplay. This absolutely gets full mark in that aspect. It's very well fleshed out, there's many hours worth of additional mechanics built on top of the unique system. 🟢 Atmosphere, Setting, and Music I really liked the soundworks in the cutscenes and intermissions. It really makes the journey following Moma diving into Million Depth feel very special and precious. 🟢 Illustration and Graphics Moma is very cute! And true pixel graphics, a rarity in this modern time. With several very pretty fullscreen CGs too, crazy 🟢 Content distribution, Repetitiveness Game feature unlocks and spread out and drip fed well. After many hours there's still new things and my interest was well sustained. 🟢 Fun Almost forgot this one The game was fun, and that's important. 🟢 Bugs Oh and this one I experienced no crashes, no softlocks, not really any major bugs. This is important because each game session can be quite long hitting an hour. Not sure if there is resume feature, I didn't try 🟡 Intensity, Fatigue I could only play 1-2 hour session each time before needing a break. 🟡 Controls You want Mouse & Keyboard, I can't imagine playing this on Controller. Spoiler-y section below --- 🟡Writing/Execution/Pacing This one is a bit tough for me to pin down on what exactly felt off. I don't think it's the localization; it's decent: no basic mistakes and I understand the story / the idea gets through. Nearing the end climax of the story, the execution or writing feels lacking: I understand the event but they didn't quite hit me strong. It still feels very special and sublime, but unfortunately the emotion it was trying to invoke gets a weak response from me. I am not sure if this is better in the original language, that perhaps it's due to localization making the dialogue lines awkward. Why is this 🟡 yellow and not 🔴 red? On a high level, I still really really love the story plot. I love the setting, and Moma's journey into the Million Depth. I think the kernel of the story is cinema material, and the delivery can be improved. It really feels very special, and I wish someday the smaller details in writing can be refined. ⚪ Closing Thought Moma is so cute! I love Moma! I want more lore about Moma! I wish I can interact and pat Moma or Hachi when they show up in the game menu. Like Trickcal maybe!
