Harmony

Bit pickups gain extra value based on pet happiness. Effect scales with cartridge level.

Harmony is a power cartridge drawn when your pet levels up during a run. When chosen, each ground bit pickup for the rest of the run gains a multiplicative bonus from your pet’s current happiness hh and cartridge level ℓ\ell:

bonus=log⁡15 ⁣(max⁡ ⁣(1,  h15))×1.5 ℓ−1\text{bonus} = \log_{15}\!\left(\max\!\left(1,\;\frac{h}{15}\right)\right) \times 1.5^{\,\ell - 1}

Multiple pickups stack their bonuses additively before the multiplier is applied. Higher happiness yields diminishing returns. The log curve naturally compresses large happiness values.
