Snake 64

Overview

This project is a complete Snake game built for the Commodore 64 in C, compiled using the Oscar64 compiler. It started from the simple Snake example included in the Oscar64 sample programs, which demonstrated basic movement and screen output. From that foundation, this project evolved into a polished game featuring smooth animation, joystick and keyboard controls, scoring, growing tail mechanics, HUD indicators, sound effects, and a refined game loop.

The game runs on:

• Real Commodore 64 hardware or FPGA C64 emulators
• VICE or other C64 emulators
