my big black hole is massive and it sucks everything in

After 50 hours, this game has been so much fun. It is unique to other idle games in the way it requires strategy. If you want your black hole to grow while idle, you better make sure there's no way your feeds will make it collapse. This gives you options: do you want to farm collapses to permanently strengthen your stats? You can set that up by turning on auto-buy and auto-collapse. Do you want to really grow and move up the leaderboard? There will be trial and error, but you'll figure it out. Overall, the game is a 10/10. Visuals are great and props to the developer for being so active with the community through the discord. I'm glad knowing the dev is keeping up with the feedback and working on making the game even better. How to Grow a Black Hole has been a breath of fresh air for me; I normally play competitive fps, but it's nice to have a game I can play that's not so stressful for once! Thanks Noah, great job and keep it up!

An honest review from an idle game dabbler: First off let me say this game is very impressive even if it isn't everyone's cup of tea. The mechanics of balancing the growth of a blackhole while not collapsing it is very unique and fun. There are some strange accusations that this game was made with AI, but I have a different take on that, which I will save for the end. Pros: Game mechanics are compelling and unfold as you play the game. First you start off collapsing your blackhole relatively often to get the prestige points. Some people have mentioned this in other reviews as a negative. I personally think its a good thing to accept as part of the core design of this game. you aren't supposed to achieve insane runs on your first play through and instead working towards that ultimate run is a very rewarding experience. The UI is clean and to the point. Fits the aesthetic of the game quite well. Preventing collapse makes the game far more active than other number goes up games which might not be for everyone but I found very engaging to optimize. Visuals are pleasing to look at though I do wish there was more of an evolution of different colors as you progress through the different mass objects. If I were to score this game I would say it lands at an 8/10 putting it in the exceptional range for this game category where the bar is very low for quality game experience and unique mechanics. I purchased the game for $3.99 and I would say that is an excellent price for the amount of content and time I am getting from this game. 10/10 on price. Cons: Tutorial leaves a lot to be desired. If you choose to play this game make sure to shift into the headspace of having to figure out what is happening. Do not expect the game to spoon feed you how everything works. The masochistic side of me kinda likes this because it reminds me of older games but that isn't an excuse. The game has an obligation to effectively communicate all the mechanics and I would say it barely passes in this area. Might run a bit heavy on lower end PCs if you have it in the background all the time. I would love to see the devs push the limits on optimizing this game wherever they can. Spicy Section: I have read a lot of the reviews and I am seeing a very strange thing occur around accusing the game of having AI art in the game, or AI UI, etc. The reason I call this strange is it looks coordinated or botted because the critique doesn't really make any sense if you know what AI games actually look like. The biggest tell of all is how many of the reviews have questionable game time on them, which makes me think that this dev got targeted and someone is trying to leverage the AI hate towards this game. Almost like its the middle ages and someone it mad an their ex so they called them a witch to get them burned alive. I personally am not educated enough on what is or isn't AI to make an educated determination here but I thought it was worth noting that some of the reviews don't look sincere and smell of virtue signaling.

It's a pretty good game, there's no AI in its creation (from what I can tell but I'm not an expert). Its can be a bit repetitive and sometimes can feel like there's no progression unless you actually engage with it actively. It is a pretty good idle game in terms of graphics and its nice to have just to have in the background while ur doing smth else. PS. I hope the developer makes the auto-buy feature so that it also buys the black hole upgrades for a better experience and everything would be perfect!

Review: A Cosmic Gem for the Second Screen I just recently dived into this game and am absolutely thrilled. The pricing is incredibly fair, and when it comes to performance, there is absolutely nothing to complain about—it runs flawlessly and buttery smooth on my setup. So far, I hasn’t encountered a single bug or glitch. A real highlight was the interaction with the developer, who responded to my suggestion remarkably fast. I honestly cannot understand what some people are complaining about. The game delivers exactly what it promises: a wonderful, charming, and casual little idle game. It is absolutely perfect for letting it run relaxed on one screen while you get things done on the other. A definite recommendation from me!
