Big fix: enemy scaling was broken — your build could hit 17,682x power but enemies only ever scaled 4.56x. Fixed by making normal mobs scale HP like bosses did and numbers scale up as well.
Nerfs: Sharper Darts & Piercing capped at 10 (were uncapped, people had 40+). Momentum capped 8 > 4. Quick Feet 6/sec > 2/sec. Enemy speed no longer outpaces you late-game.
New stuff: 5 perks, 6 shop cards, geometric shop pricing, more late-game danger (contact dmg, boss aggression), better fireworks/hazard variety, bosses now have colliders, better hazard identification as well as some new hazards, pots on counters.
Bugs fixed:
Ricochet did nothing past 1 stack — capped, moved to rares
Orbiting Utensil didn't actually scale on bosses — fixed
Pork City 5 had no hazard, defaulted randomly — fixed
Grease puddle visuals misaligned — fixed
Controller could buy stuff you didn't pick — fixed
Second Wind could roll twice — fixed
Enemies could outrun you — capped
Enemy count doubled too early (wave 3 not 20) — fixed
Blank level loads — fixed
Explosive Impact lag — optimized, same behavior
