Alley Cat is a beloved classic DOS game originally released in 1984 by Synapse Software and later published by IBM. In the game, players take on the role of Freddy the cat, an adventurous feline navigating urban environments filled with various challenges. From sneaking into apartments to steal fish to dodging pesky dogs and romancing other cats, the game delivers a unique and fun experience with its charming pixel art and simple yet engaging gameplay. Over the years, Alley Cat has remained a nostalgic favorite for retro gaming enthusiasts.

Recently, Alley Cat has been redesigned to support modern devices, including touch screens and mobile phones. This update allows a new generation of players to experience the game without the need for a physical keyboard or joystick. The transition to mobile devices brings a fresh take on the game while retaining its original charm and mechanics. With responsive touch controls, players can now enjoy Freddy's feline escapades on their smartphones and tablets with ease.

One of the challenges faced during this redesign was figuring out how to handle the game's initial keyboard-based input on mobile devices. In the original game, players needed to press specific keys to start the game, such as ENTER to begin, N for "Not Joystick" mode, and K for "Kitten" difficulty mode. Without a physical keyboard on mobile devices, this presented a dilemma: should an on-screen keyboard be added, or was there a more seamless solution?

After some brainstorming, the idea of automating the game's startup sequence using JavaScript emerged. The following script was created to simulate the necessary key inputs at the start of the game, ensuring that players could jump right into the action without manual intervention. The script sequentially simulates the key presses for ENTER, N, K, and another ENTER, with short delays between each step to mimic a real user's input.

// Simulate keys in sequence with delays
const simulateSequence = async () => {
  await new Promise(resolve => setTimeout(resolve, 500)); // Wait 500ms
  simulateKey('Enter', 'Enter', 13); // Simulate ENTER

  await new Promise(resolve => setTimeout(resolve, 500)); // Wait 500ms
  simulateKey('n', 'KeyN', 78); // Simulate N

  await new Promise(resolve => setTimeout(resolve, 500)); // Wait 500ms
  simulateKey('k', 'KeyK', 75); // Simulate K

  await new Promise(resolve => setTimeout(resolve, 500)); // Wait 500ms
  simulateKey('Enter', 'Enter', 13); // Simulate ENTER
};
 

This approach not only eliminated the need for an on-screen keyboard but also provided a smooth and effortless experience for players, making it feel as if the game starts naturally with minimal input required. The implementation was a clever workaround that allowed the core experience of Alley Cat to be preserved while modernizing it for today's touch-enabled devices.

With the successful integration of the automatic input sequence, Alley Cat can now be enjoyed seamlessly across various platforms. Whether playing on a desktop with traditional keyboard controls or on a mobile phone with touch-based interactions, the experience remains true to the original game. The enhanced accessibility means that longtime fans and newcomers alike can dive into the game with minimal hassle.

Overall, the redesign of Alley Cat has been a fun and rewarding challenge, bringing new life to a retro classic while embracing modern technology. The game's quirky charm, combined with its updated compatibility, ensures that Freddy the cat's adventures will continue to entertain players for years to come.
