- Genius Bonus: The game is playable even if you lack mathematical knowledge, but many concepts including the formula, theories, and achievement names will require high-school or even college completion to fully recognize how they work and what they reference.
- Low-Tier Letdown: Theory 8 has painfully slow growth prior to reaching e60$, to the point that it's much quicker to sell it immediately and assign students to other upgrades before reaching R9 at $e14K, at which point the growth of each theory is sped up enough that T8 is doable.
- That One Level: The gap between ee4800$ and ee5000$ (where you unlock the first theory) is notorious for getting players stuck. It's often necessary to optimize things like starsnote , studentsnote , and also turning on the ad reward, but even players with a perfect setup sometimes have to grind a few days.
- That One Sidequest: Theory 5, unlike the rest of the theories, cannot be overnighted (meaning it requires active play to get the best results from), and requires the correct combination of autobuy uses so it doesn't stall.
- Woolseyism: The achievement for earning ee20000$ is called "Stonks" in the English version. The Polish version changes the name to another money-related meme that'd be more familiar to them "O, pisiąt groszy!"
