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.
For the price point, you get a LOT of bang for your buck. There's a lot of game here for very little money. The graphics are gorgeous and the sound is really really good. However, there is a big issue in that it is extremely difficult to see how the various systems interact. BH Mass, Disk Matter, Accretion Energy, and the Disk Pressure all interplay in ways that are completely opaque to the player. This means that most the effects and consequences of the black hole powerups and improvements are effectively meaningless to me. Since I don't know what they do, it becomes a matter of "click on whatever is cheapest". The UI is pretty good although the vast majority of the game is spent in a little tiny scroll box on the right side of the screen (black hole powerups). One big improvement is making that easier to navigate. Another large wart is the "curvature research" screen. It's very pretty but the items are spread WAY apart and it is very hard to navigate. Tighten that up. A lot.
I don't know if a lot of these folks leaving reviews have actually played AI games, but this is NOT AN AI GAME. It's kind of weird to even assert that, nothing about the UI has the standard AI dev features, save for *maybe* the fact that the curvature upgrade menu layout is a little insane. Even then, you can see the vision, it's meant to provide clarity and distinction between upgrade paths so that it's clear what does what. This is a pretty good idle game, I can't speak to performance issues, I'm playing it windowed because it's an idle game, and if you're not playing idle games windowed you're probably not human, but I'm having a great time with this one. Don't normally leave reviews, but the chilling effect that bullying solo devs can cause is really scaring me. You can hate on devs all you want, but just remember, if solo devs are too scared to make games because they're worried about being accused of using AI, we're going to lose a HUGE part of what makes gaming so special these days. Undertale, Balatro, Ultrakill, Crab Champions, we're not getting anything else of that caliber if you guys scare solo devs into inaction.
Game is as advertised, fun idler. I do have some performance issues for some reason, I have a quite beefy PC (specs will be listed) and I only seem to get ~30 fps when tabbed into the game, however when my cursor is moved outside of the game screen I get a proper 200-300 fps. pls fix :) Edits: 1. This is an issue with the fullscreen mode of the game. If you are having the same issue, take the game out of fullscreen mode. 2. Formatting.
