Double Snake (SEGA Genesis / Mega Drive)

About

Double Snake is a 2 player-focused homebrew Snake game for Sega Genesis / Mega Drive. There are additional tiles, bonuses and effects compared to the original Snake to spice up the gameplay.

It is a port of an earlier PICO-8 version (available here https://www.lexaloffle.com/bbs/?tid=145602).

Game modes

• Versus — two players compete in rounds. The first player to win ten rounds wins the match. Could be played against CPU or human player.
  
• Co-op — two players share a score and work together on the same field.
  
• Solo — control one snake, collect apples, and chase your personal best.

Each mode supports:

• Small, Medium, and Large fields
• Slow, Medium, and Fast movement
• Optional starting Shields
• Unique maps with randomly walls, ponds and mud for each new round

Bonus apples

Dark bonus apples increase the score without growing the snake. Each one activates a random effect:

• Picnic - adds nine apples to the field.
• Shield - protects against one wall collision. Multiple Shields can be collected.
• Darkness - hides most of the field except the area around snake heads.
• Blindness - obscures the area around the affected snake.
• Pond - adds water where snake-to-snake collisions are ignored.
• Shock - temporarily stops a snake.
• Slow - temporarily reduces a snake’s movement speed.
• Body Switch - exchanges the two snake bodies.
• New Wall - adds walls to the field.
• Wall Break - removes existing walls.
• Fire - sets snake on fire. It will burn to death, bit-by-bit unless snake jumps into pond.
• Apple Snake - infuses snake's body with apples. If somebody bites the Apple Snake, it loses portion of its body instead of dying, dropping it as apples on the ground.

Shock, Slow, and Body Switch are available only in two-player modes. In Versus, negative effects target the opponent.
