🐸 Frogger in MIPS Assembly

A simple version of the classic Frogger game built entirely in MIPS Assembly, designed to run in the MARS MIPS Simulator.

This was a fun and challenging low-level programming project with sound, animation, keyboard input, and visual display — all built from the ground up!
