A new Fine Tuning system has been added to the game:
You can spend credits to tune your core's resonance at a curve.
Each fine tuning improves your stats by a small percentage, but the effect scales with the upgrade materials you gather and apply throughout your journey, along with your active consumables.
Improving resonance also slightly reduces the percentage of damage you take.
Additionally, more upgrade materials have been scattered throughout the game, along with several balance changes and bug fixes.
