Alright, I love maths and fractals and big numbers, but this game just didn't let me experience it. It starts with little to no explanation, things already happening, and I haven't even read the wall of text on the buttons I'm supposed to press. And once I read it, it doesn't help, so I end up pressing any button I can, favoring the bottom ones as they seem to be stronger. What's going on? What are the rules? Where is the fractal in these flashing dots and numbers?
A lot of incremental games start much slower, from a not-automated point. Imagine if you had to manually and carefully place a branch on a tree, and then observed that branch being duplicated many times on each copy of the tree, with no rush. That would make a meaningful difference.
Also, you can't just calculate these numbers. I worked on a similar project (with much higher numbers though) and implemented a system that gradually shifts from calculating to estimating, while keeping same level of precision. And once you have to show hundreds of things on the screen, you have to show a pre-rendered picture of hundreds of things instead. I don't know how your game works, but it lags and eventually crashes, so if there are optimizations it's not enough.
Despite all that, I think you did a great job actually. First, you had a courage to make a game like this. Then you made it actually work (if not crashes). And you made it look good, with solid style and enough of crazy visual mess to feel how big the numbers are. I couldn't stop playing it, pressing buttons and watch, through all the lagging, until it completely crashed. It's sooo addictive. In the end, it might have missed explaining fractals to the player, but it's a very fun game, and I enjoyed my time playing it.
Good luck with whatever you decide to make next!
