Most "improvement" hacks add palettes, custom sprites, or brutal difficulty. does none of that. The "3C" stands for Triple Coded Calculus . The "Delta" refers to the change in velocity over time.

This is a —a full reconstruction of the original 68k assembly into readable C code. The team (three anonymous devs using the handles vector , friction_man , and Dr. Logarithm ) didn't just change level layouts. They changed the physics header .
