Exponent idol
Still blown away that this game is fundamentally astonishingly fun
操作性最悪
つまらないパズルやらそうとするし理論とやらにたどり着くまでの虚無期間がめちゃクチャ長い 変数の自動レベル上げの各項目のチェックをいじろうとすると高確率で勝手に全部チェック入れられたり外されたり最悪
Fun math related idle game
Game gets going quick. Progression is nice so far. Doesn’t lean too heavy into the math, but the complex equations can be fun. Just lacking a bit of options at the moment to keep it engaging.
I hate how they use e
1e3 is supposed to be 1 followed by 3 zeroes but this game doesn’t understand that at least initially
?!
How do you unlock chapters?!?!!
Worth the investment
Phenomenal game. No unnecessary ads. One purchase for permanent ad block ($2!) and a silky grey atmosphere. Wonderful idle experience overall. Highly recommended.
Don’t waste money
Constantly need to restore purchase, constantly getting hours of offline rewards nerfed due to my purchase not being restored. Very disappointing to have one crucial IAP and it’s barely functional.
Great game!
I love the game. Initially, I thought it would be very hard to enjoy the game, because the goals take be exponentially longer time. I'm currently on my 6th supremacy, and It waiting to see what graduation and theories have to offer!
Challenge to me
Make each puzzle smaller. Easy- 2x2 Medium- 3x3 Hard- 4x4

Honestly, its really fun
I love the incorporation of math in an Idle game. I’ve seen something similar before, but never to such a degree. Bravo

敬い
Beautiful.
I love the look of everything. It’s almost ASMR-y to have it running in the background. Suggestion, not complaint. Maybe different color palettes, adjustable scales of the different lines of algorithms, exponents, numbers running.
As a math major, I don’t get the point of this game.
So it’s basically a default clicker game with a “smart” approach in which you see a formula that shows how exactly your score goes up. In the preface it asks if the formula converges so I was expecting a lot more fun from this story, but there’s clearly nothing to do with convergence. I’m really surprised how this game is 5 star. Seems like people just feel smart playing this game? Hilarious
パズルが無ければ…
惜しかった。 シンプルで綺麗なゲーム。 個人的にはパズルが無ければ★5の作品。 星のリソースの為にパズルをダラダラ何度もやる必要があることが発覚してやめてしまった。 メインのみで星のリソースが得られるようになったらまた遊びたい。
Awesome game but 1 thing...
Awesome game but r9 swapping is a huge pain - auto r9 swapping needs to be an unlocking feature. Make it parameterized - % of last max, amount of time, etc. until next prestige or supremacy.
If you wanna waste your life by all means download
Awful progression 100% don’t recommend
A small suggestion
I feel the way the db Graduation Research is handled should be changed because I did the math in Desmos and the highest nember it would let me try as an input resulted in an output of about 56 meanwhile I can just Research the Star one more and multiply everything by over 1.61 million and quickly rising. For reference, for every Research into Stars, I need to do FOUR Research into db, which is NOT economically viable.
Fun game if you like large numbers
Suggestion for the devs: How about doing something similar that is based on the fast-growing-hierarchy? I know the maths is much more advanced but this kind of game might make it accessible.
Best incremental game
The mini games are honestly my favorite, they are so clever. The idle game mechanics of exponential idle are amazing and endless, too.
矢印パズルが出来ない
いいゲームなのに150この星を払ってやる矢印パズルっていうのがあるけど攻略を見ても必ずクリアできない盤面になる
Fun game!
But it seems that there are two spaces in the app title. That’s my only problem with it honestly
Great Idle Game
So much fun playing this idle/incremental game. Loved the theme of it and the fun little tweaks on the idle format.
Overrated
Mid idle game with pacing destroyed due to star shop. Edit: my progress got wiped very cool.
数字が見づらい

good game
I love exponents
Not forgiving at all
I have two young kids who frequently get ahold of my phone when I’m not paying attention. Turns out they ended up changing the date to 2 weeks in the future. When I set it back, the game said I could either be locked out for 2 weeks, or reset my game entirely. Devs could have just programmed the game to revert idle progress when a time change happened but instead the lazy devs have it set to ban you from the game. Looks like I can’t play since I have kids. Was a fun game while it lasted but I can’t promote a game with such an unnecessary and harsh function.
Good game, but progression after theories is insanely slow
After unlocking recurrence relations, my progress has just stagnated. I’ve tried using 100s of thousands of stars to try and upgrade variables and many different combinations of student upgrades, but at this point every prestige takes more than a day and it’s been a while since a supremacy. I’m positive that I can be doing something better but the game gives you very little instruction. Still, up to this point it’s been a nice game when I’m bored, and I appreciate how there are no ads unless you initiate them.
Shut up and take my money!
Genuinely clever incremental game. The math looks intimidating but you don't actually need to understand it to play and progress — though it might make you curious enough to learn. Clean design, no predatory monetization, and it respects your time whether you play actively or let it idle. My one complaint is that I'd happily give the developer more money than the current IAP options allow. If you ever add a bigger tip jar, I'm in.
Game just dies out
After you supremecy for the first two upgrades, it takes 5 days to get the next. I enjoyed the limited ads and it was fun, but there is just literally no point to opening the game. Theres nothing to be done but wait wait wait. Nothing to click to accelerate it. Just wait wait wait. Literally just log in once a day and say "cool, guess I will log in in a couple more days to see if I can do anything.
ボイスオーバー環境で押せないボタンがある
タイトルの通りプレステージやミニゲームや設定など主に画面下部にあるボタンがボイスオーバー環境で押せないので押せるようにしてほしい。ミニゲームはボイスオーバーでプレイできないのでプレイできるようにしてほしい。
Sounds design
The actual gameplay? Totally awesome. The design of the UI? Love it. The sound design though? I can’t describe it. It’s heavenly. Even if you don’t like idle games, get the game JUST so you can experience the awesomeness that is the creamy clicky sounds when you tap stuff. Even if this was just an app with a button for the sound, I swear I would use it constantly while doing other stuff. It makes my brain melt. I wish I could give it six stars.
掛け算も出来てない

Really Fun Game
Fun idle game with a nice story line, the new unlocks throughout the game keep it fresh, and kept me hooked on this game while I got bored of other idle games. Unfortunately I was messing about with date and time in my phone for a different game for some fun, and when I came back on the app I was locked out for 5800 days… I understand this is a necessary feature to stop time change exploiting, but an in game penalty that allows you to continue playing the game, but maybe reducing you psi count or something like that might be better then forcing a complete reset of the game. While this frustrated me greatly, luckily I wasn’t too far in the game (only about 3hrs of actual gameplay) and enjoy the game enough to want to get back my progress. Overall a very fun game, but the anti-time cheat penalty is very harsh.
One of the best games I’ve played
Absolutely genius. I’ve not had more fun in a mobile game, figuring out the puzzles to make the function grow. Please expand this game with more content.
Prinzip nicht verstanden
Obwohl ich ein hervorragendes technisches Studium habe. Tut mir leid. Das Spiel hab ich nicht verstanden...
Huh
Strange
