After putting several dozen hours into this game I'd like to give my opinion on what makes this game enjoyable and how it can be improved.
The early game is amazing while you're first learning about what systems exist and you feel the scope stretch outwards as you grow. There is a curious "I wonder what gets unlocked next" which carries through your mind and keeps you going.
The early-mid game when you are nearing the end of your first universe and start bumping up against the limit of expansion is a bit of a let-down. There isn't much of a reason to scale into clusters and superclusters as the lack of any structures that can be built on those scales makes progress there tedious.
The mid game when you're first creating new universes but have not yet gotten enough dimension remnants to justify creating a new dimension can feel like a slog. The only time you get to experiment with new content is between universes, and that's several hours between. Even when you're able to alter fundamental properties you're really suffering for probe points and I can imagine some players feeling like it's not worth repeating until they unlock dimensions.
The mid-late game when you've finally gotten enough dimension remnants to create a new dimension can be heaps of fun. The players who stick with the game to this point and get the curtain pulled back on the math can see a distant future where they can break this game's mechanics over their knee. If they invest poorly and get stuck repeating the mid game, I can imagine a lot of people quitting here, but those who are able to find an expanding niche to exploit... oh-boy...
The post-late game, when you have invested hundreds of thousands of dimension remnants, are able to complete universes in less than an hour, and can reap exponential amounts of remnants every time you create a new dimension is when this game reaches 10/10 territory. Does having 10000+ universe value (after having reduced the cost of it to the floor) feel broken? Yes. But when you've spent days struggling against the grind the ability to drop so many dimension remnants that you can minimize the building cost down to almost nothing, or make the probe point cost of time speed insanely cheap (zoooom!) or pump pickaxe speed up so high that you can crack a planet in half within the first 5 minutes of a new universe is, in my opinion, where this game really hits its stride. Incremental games like these live or die on whether you're able and how enjoyable they are to break. And this game feels insanely fun to break.
