It's so nice of Calli to give all those boosts. That, or she likes yeeting medium people almost as much as small ones.
Minor note: The upgrades feel really small. A 10% boost to something that might show up when I need it, and that I might hit when it shows up?
Maybe they'd feel less small if they came with some modifications to the probability of related things showing up? Like, the Calli-yeet-booster also increases the chance of Calliopies spawning, or the meatball-slow-reducer replaces some Baes with meatballs, or something like that.
