Reviews
This is a re-review after having 100% completed the game. My opinion hasn’t changed, but I have more to say. My playtime has all been on steam deck and it runs perfectly with it. This game is a real hidden gem. It mixes puzzling elements with reactive gameplay well, and it manages to avoid frustration most of the time. There are a few levels that are more focused on the dodging gameplay, but they are few and far between and in my opinion don’t detract from the puzzle elements at all. The visuals aren’t anything to write home about, but they do a good job at expressing what is happening at a glance. There is one enemy late game that relies on visual obstruction, but it never requires you to memorize long sequences of actions while blind. The enemy variety is amazing. There are a total of 20 different enemies and they all behave DRASTICALLY different. The only thing I would want differently is for them to mix with each other more. No level has more than two enemy types, and different colors of enemies never mix which I found disappointing. However the dev did say they were working on this in a future update. The level fail condition is running out of time, and on the default difficulty, getting hit by an enemy doesn’t instantly fail the level, but gives you a “half-complete” level after it’s over. I played on the difficulty that makes getting hit an instant death, and it feels like it’s the intended way to play. The story is… well… here. After clearing a level, you get a couple paragraphs of text to read. For most levels, this is lore. It does a great job of world building, but I found it difficult to follow the specific stories of the hacker(s). The fact that I can’t tell how many there are probably goes to show how little I understand. The levels that introduce new enemy types have special entries that give background details on each one. Those were my favorite to read Lastly, I would like to talk about this games difficulty curve. You can use an assist feature to skip levels, but if you don’t, every single level is required to beat the game. And if you are a gamer with lots of pride (like me) you can hit a brick wall and be too stubborn to skip. The first couple of levels do a good job at explaining the game’s main mechanics. After that however, the game goes into a cycle of introducing a wave of new enemies across each megacorp and giving 3-5 new levels for each. The last of which is considerably harder than the rest, usually featuring 2 enemy types instead of one and being a lot tighter in movement. The first time I got stuck was on levels 313, 411, and 511. This is a huge difficulty spike. I did finish these levels eventually, but It never felt like I found the “correct” solution. After these however, with the introduction of new enemies, the difficulty drops to be the about the same as the tutorial for a couple of levels until you get back to the end-of-section difficulty spikes. The end of the game is also disappointing, the last two levels of each megacorp combine two sentinels, but I found these levels to be weird with difficulty. Most of them feel like they should have been much earlier. They are complex, but they don’t pose as much of a completion challenge as the three levels I mentioned that come much earlier in the game. Level 525 however definitely stands out as being much harder, and is the good example of a final level. The very final level of the game is 125, and it is so wierd. It features one sentinel type, one color, and none of the special tile mechanics aside from doors. It isn’t that hard either. Most segments can be easily accessed, and the one difficult part could be brute forced on the fly. I definitely feel like this level would have been way better super early into the green section, and it should be replaced with a more fitting and climactic final level. Overall, I do recommend this game. I know most puzzle players don’t like reactive gameplay, but if you do, this is a great example. There are some problems with difficulty, but if you can get over the hurdles mentioned earlier, you can probably beat the whole game and enjoy it while doing so.
unique puzzle game where before & after levels you get to read snippets of story about different people and the main megacorporations running this world, they both work together so well to keep me hooked like what do you mean this megacorp planned to make most the world uninhabitable through climate change so it could develop the solution and control the remaining population of just 1 billion? thats a sick intro context and i hope to see the story lead somewhere hype where these hackers really do take it all down and "reset" the world
[h1][b]需要实时解谜的黑客模拟器[/b][/h1] 《NULLPTR》是一款黑客主题解谜游戏,其不同之处在于是实时的,骇入的过程中需要避开各类防御元素,加上多个机制的引入,玩起来非常特别。 本作采用了极简风格美术设计,纯黑色背景加上红黄绿等不同区域的主题色,再配合几何图形构成的关卡,看起来还不错。 游戏的目标是突破防御机制的封锁,入侵服务器获取数据并撤离。 每个关卡开始后会看到各式不同颜色的节点,与其中高亮的节点互动后系统便会显示出所有路线,沿着路线行动,找到服务器互动然后返回即可。 经过了教学关后,系统开始引入了各类新的机制,比如限制时间的追踪器,如果单次行动时间过长便会失败,这种需要在中途找到节点暂时下线然后重新上线。 随后还会引入会不断巡逻的哨兵,其行动范围是可见的,但路线需要自己摸索,多次尝试下便可以掌握这些信息,随后便可完美避开。 还有一种需要玩家按照一定顺序激活的锁定节点,这个过程会多次辗转于节点间,玩起来颇有推箱子游戏周转的感觉。 除此之外,还有各类机制,游戏以此打造了丰富的关卡,整体表现还不错,目前无中文,期待汉化。 [quote]热爱游戏,畅玩游戏,分享游戏,专注鉴赏评测与深度解析 欢迎关注[url=https://store.steampowered.com/curator/44110339/]游理游据[/url],走进游戏世界,品味第九艺术[/quote]
Nullptr has an interesting premise and some cool mechanics. I haven't gotten that far into the game yet, but so far the puzzle design is good and the story is surprisingly compelling. I'm looking forward to playing more.
An extremely cool and fast-paced puzzle game. There's lots of story here, too, for those who are interested. It's a very action-y puzzle game, where your timing and speed matter a lot. Would LOVE for this game to get leaderboard support - feels like it's perfect for speedrunning and competing with other people's times.
It is a really fun hacking game with some good action and timing elements.
Still early-ish in the game, so will likely edit this review, but wanted to boost the numbers somewhat. The game's super minimalistic in presentation, but does a lot with what it has. The cyberpunk dystopia fits neatly with that, and the writing has kept my interest as well - it's your only reward for doing a perfect "ghost" run of a stage. As for the puzzles, they too are usually fairly minimalistic, quick to solve once you understand what you need to do (though there are exceptions, e.g. 207 took me 5 minutes and a lot of it is trivial fiddling around). Sometimes the fact that a ghost run is always possible is itself a clue that you are missing something, the game doesn't ask impossible feats from you. Overall, you have 125 clever, bite-sized puzzles in the game. Looking forward to going through the rest!
The Puzzle design and story are really neat. But the puzzles have a serious execution element, with multi part executions and usually pass-fail checks at every step where if you fail you, at minimum, miss out on half the story of the level. Overall I found that element fiddly and frustrating, but I would still recommend if you think you have greater patience or skill for it. Maybe I will go back and finish the game eventually for the story, but at 30+ tries, with tries taking just enough time to be really frustrating when you get dinged, I just don't want to waste my time banging my head against the wall when I figured out the solution 15 minutes ago and the only thing that is keeping me from the next puzzle is rote execution.
I still haven't played the game much, but I enjoyed the demo a lot. It's very stylish and varied.
Belle pépite, beau gameplay, beaux puzzles.
