There are a lot of idle games you haven't tried. While this does rank fairly high, maybe top 25% or top 20%, it's insulting to a lot of other creators who have worked harder, made better, and made lots of content to have this game that has no graphics besides white buttons, gray tabs, and a gray background, as well as only 6 tabs total and 2 hours of playtime max, be higher than much more complex, longer, and overall significantly better content.
One example is A Dark Room. While it is simple and only has text graphics, it has a story to go with it, and doesn't just have the same boring stuff for the entire game. You can change the color of the background, if you want. You can embark on adventures to get more materials. There's no basic prestige systems, nothing's actually that confusing, and it has more quality content than this.
Another example is The Prestige Tree. Its entire point is to have the user prestige, upgrade, prestige more, maybe upgrade some more, and then unlock a new way to prestige. I think this game might've been based off of it, but it's not very clear because of these basic graphics vs the colorful graphics in Prestige Tree. Like an upgrade tree in most RPGs, Prestige Tree's UI eventually forms a tree-ish shape after you unlock a few nodes (different ways to prestige and make more progress). Also, most nodes unlock new playstyles to go along with them, like bars to Balance, Magic power to buff other nodes, and more! There are challenges called Hindrances, which are ways to upgrade how many Points you get, as well as upgrade other nodes. Another feature is that you can use buildings in some nodes, which also buff other nodes. Sometimes these buildings can even buff themselves, like the Quinary Space Building, which adds 2 levels to all previous buildings (the Primary, Secondary, Tertiary, and Quadrinary Space Buildings). There's also an achievement system; you'll fill them out relatively easily as you go along your journey to complete the game (get e3.140e16 points). Some achievements are just there to show, but some achievements will actually help you and buff the various nodes you've unlocked. For example, in the early game, you'll only have Points and Prestige points. Points automatically generate when you buy the first Prestige upgrade, but Prestige points require you to sacrifice Points. Prestige points, however, are gained very slowly. However, there is an achievement in the early game called 'Prestige All The Way' that lets you get Prestige points 10% faster when you get all 3 upgrades! Another example is 'Prestige^3', an achievement that lets you unlock 3 more Prestige upgrades when you reach 1e45 Prestige points (by now, you've unlocked the next 2 nodes, Boosters and Generators, which will help a LOT). Overall, this game is extremely fun and has significantly better content than this.
You've heard of Antimatter Dimensions. I'm not explaining it to you.
There are many more games that I could've explained to you here, but if I go any farther I'm probably gonna hit a limit (why did I explain Prestige Tree so much?) anyways, have a good time rediscovering the top 10%, I wish you luck!
