Frog! is a game written by Bob Carr and published by CodeWorks - Cursor for the Commodore PET. It is a simple, text-based game where players control a frog attempting to cross a busy road or river, avoiding obstacles to reach a goal. The game is reminiscent of the classic arcade game *Frogger*, adapted for the limited graphical capabilities of the Commodore PET.
The Commodore PET, released in 1977, was one of the earliest personal computers, and games like Frog! were designed to leverage its text-based display. CodeWorks - Cursor was known for producing software for the PET, and Bob Carr was one of their developers, contributing to the library of games available for the platform.
Specific details about Frog! are scarce, as documentation and preserved copies of the game are rare. However, it is recognized as part of the early wave of home computer games that laid the foundation for the gaming industry. The game's simplicity and reliance on text-based graphics reflect the technological constraints of the era.
