Mio is a great game. I like sci-fis and i enjoy metroidvanias. This game has both of it. The story is pretty good tho(i'm trying not to spoil things XD). If you like a good stories, banch of great mechanics, challengenig platformer, various locations and bosses, than you will enjoy this game as much as I did :)
Very good metroidvania and absolutely gorgeous too. Loved the movement mechanics.
恶意满满的,劳没做够可以来玩
game is goated except for that one boss above metropolis ♥♥♥♥ that boss.
Very gripping story, solid controls and the art direction and environments will definitely make an impression. It's a bit hefty with the platforming, Hollow Knight (Path of Pain) lovers will feel right at home. Albeit not quite as challenging in every part, it will definitely keep you on your toes. In summary, a VERY well thought out Metroidvania with some of the most intriguing story telling and mechanics I've ever seen. Highly recommended!
Absolutely adore the inspirations this game takes as well as the music. Gameplay feels balanced and even though sections can feel very much like a souls-like experience, I am all for it.
I haven't been this invested in a game in a while. Due to some of the reviews I was apprehensive at first, but none of it turned out to be a bother for me personally at all. There are some wonky parts for sure, but the vast majority of the game is absolutely amazing. The combat and movement is insanely fun once you get the hang of it, the story is riveting and moving, and the soundtrack is absolutely phenomenal. What a fantastic game.
不看攻略没法玩,太多隐藏,指引也很差,经常卡住不懂要去做什么,连很多正常的路线都要隐藏起来
好评是不可能好评的,游戏后期的跳跳乐太多太长跳完也没什么正回馈,没有让人振奋的剧情,没有强大的能力,只有更多的跳跳乐。这游戏属于典型的创作者孤芳自赏沉迷于自己的艺术,一小撮玩家在那鼓吹什么2026最好的银河城,地图设计远超丝之歌云云,实际销量惨淡最终制作组大裁员,让人哀其不幸怒其不争。
This is an exceptionally beautiful game with a lot of content, so much so that I did not think the game would have as much as it did going in. The environments and music are all so good to hear and watch, and there is clearly a lot of effort put into the storyline and general worldbuilding - which while not mind-blowing was very touching and poetic, and very rarely did I see anything that pulled me out of the immersion of the world. There is also a ton of collectibles and minor upgrades to collect, as well as great major movement upgrades (for the most part) - all things that result in a great Metroidvania experience. Truly, this is a game that all fans of MVs should play, despite all I'm going to say below. I have two major caveats to this positive review, however: 1) The majority of endgame content will rely on you doing some really very intensive platforming. Honestly, I think MIO may be one of the most demanding platforming games I've ever played. I'm fairly certain just to get to the normal ending you need to do at least 2 pretty tricky platforming sections: If you want to go for 100%, you are going to have to do SO - and I really mean SOOOO - many, and they are brutal. I have calluses on my thumb from them! I absolutely recommend for all players using the difficulty adjustment that gives you regen of 1 extra health when you stand still for a long duration - not because 'it's just too hard so you should cheese it', but rather because you will have to redo huge amounts of trial-and-error platforming for hours at a time without it. Some of the platforming gauntlets were really fun - others really weren't. Which brings me onto point 2: 2) This game is unfortunately marred by the fact that it is not very respectful of the player's time. There are huge, meaningless runbacks for bosses, often with mandatory elevators that you must interact with etc. to return to boss fights, very regularly. It's not like they offer any challenge either, they just waste your time. Additionally, every boss will have an intro sequence and you can never skip it. And then in terms of platforming - there are often huge long stretches of platforming without checkpoints (or even places to stand!), and despite the regen upgrade/difficulty adjustment being essentially mandatory to do them, cycle-based hazards don't take that into account, so you have to sit there and wait for another cycle of the hazard once you've regen-ed. It just made me feel miserable man, all that time wasted until I got the right pattern down, with no meaningful shortcuts to cut away at completed sections (there were a few, but not enough). I still highly recommend this game to most players. But beware, ye completionists - this is a mostly fun game to get 100% in, but it only feels that way after you've done it... and it will feel miserable sometimes during the process.
