Hot Takes: Platinum Edition
Protectors cause Shotguns, not Black Hole.
Cells still >>> Coin.
Max Interest and Cash Micro aka playing the game is still the most impactful strategy.
Card Slots minimum needs to be 14, or you're severely limiting aspects of your Tower. Further (or build compensation to intentionally use limit aspects) Slots result in "extra" abilities that only have high-level or niche usage.
Nuke is the single most irrelevant thing in the entire game, ya? Even with keys?
Its nasty hot to get to Platinum in ~90 days.
