TLDR : a Maryjane gardener's Metroidvania, with periodic scripted partial resets. Big map, good gameplay. Visuals, lore & atmosphere are best described as "far out". ------------------------------------------- Blabla : this is NOT a roguelike / roguelite, not in the slightest. Anyone calling it such is uninformed / basically just gave up at the first scripted reset. This is simply a standard Metroidvania that uses "cycles" as a plot device. Each cycle opens up a new path / a new area, where your next objective lies. They also reset your character, true, but re-unlocking your upgrades is easy. You get to "lock in" upgrades quite early too, don't be fooled by mis-labels. Play the demo to see if visuals / controls work for you - buy the game if they do. -------------------------------------------- Personal Verdict : 8.5/10 so far will no doubt edit later / upon completion. Not Hollow Knig
I just want to explain the negative reviews so people won't skip because they will be scared. 1. The loops and reset and starting from scratch is really not bad. You can lock some skills so you do not start each reset without them. Also the loops make sense lore wise so they are not as annoying as in roguelikes/lites 2. Planting seeds was not so fun for me but it's not annoying, nor it is difficult to understand. You can't plant wrong, because when you make mistake, you can dig up the seed and try some other seed. Also after some time you do not have to wait one loop for seeds to bloom fully. 3. Annoying background not knowing what is interactable is weird statement. I never had a problem and never miss something. I usually didn't notice the background awesomeness from time to time and also there is accessibility options and you can make background less vibrant. 4. You need different
Ultros looks like a metroidvania, but is not entirely one. You get double jump relatively early... and soon after that it's taken from you. Yeah. It's a time loop where you're constantly thrown back to square one — which includes losing your abilities and even your weapon, so you have to get them again each time. It feels disempowering, to say the least. So much so that I considered refunding when it happened for the first time. But the game's acid aesthetics convinced me to push on, and in the end I think it was worth it. The game is visionary and has a bunch of unique ideas. Just don't go in expecting a classic metroidvania. It's also a roguelite — in that "the cycle starts anew" and your progress is reset after killing each boss. Except not really: each cycle also changes shortcuts and generates new events, and the level design around the zone you begin in is nothing but stellar, sk
⚠️ ⚠️ READ THIS BEFORE GETTING THE GAME — MAJOR BUG WARNING ⚠️⚠️- SEPTEMBER 9th - 2025 *100% achievements done after replaying with manual backup saving for safety* TL;DR: A common Metroidvania action (dashing back into a room you just left) can corrupt all your saves. I lost 16 hours of progress. Wait for a fix before buying. Another players already stated this in the foruns but with no answers from the devs to this day. Full explanation: It breaks my heart to give this game a thumbs down, and it’s probably the most controversial one I’ve ever written, because I LOVED this game. But there’s one EXTREMELY decisive reason for my rating: an UNACCEPTABLE, GAME-BREAKING BUG people need to be aware of. I wish I were using this space to talk about everything I loved in Ultros. Instead, I’m forced to warn others. I REALLY HOPE the devs fix this soon, so I can change my review. THE BUG: I
Perhaps I went into Ultros with misguided notions. Perhaps I just wasn't patient enough with the inversion of genres and mechanics the developers were going for. At any rate, Ultros turned out to be a game of diminishing returns for me. The psychedelic art is certainly one of the game's initial draws, as is the fabulous music, which can easily evoke harmony and folly within a few note changes. Upon reading that the game could be played as a pacifist, I instantly became keen on a game I had otherwise been holding off on for a few months. After all, I had several new metroidvanias to consider in 2024. Perhaps I misread the article because upon starting Ultros, I was surprised that combat was seemingly the only way forward... at least for a time. Once a few loops are completed, the gardening mechanics begin to unfold, and your non-combat options with it, but this comes late enough in the g
Right, so Ultros. It looks like a metroidvania, and for about ten minutes it lets you believe it is one. You get the double jump nice and early - lovely, you think, we're off - and then it takes it away again. Yeah. Gone. And your weapon. And basically everything. Because it's a time loop, isn't it, so you keep getting flung back to square one like a toddler who's knocked over his own tower of blocks and has to build it again. Every single time. It's disempowering. That's the word. When it first happened I genuinely sat there with my finger hovering over the refund button, thinking, "I've paid money to be robbed by a cartoon." But then the game does this thing where it's so unbelievably gorgeous, all acid-trip colours and swirls, like someone melted a fruit bowl in a lava lamp, that I thought, fine. Go on then. And I'm glad I did, because it turns out it's actually brilliant. Visionary,
