2D TD Game in Go for Demo Purposes

Primary LanguageGo

Ridmarsh’s Defense

Minimal TD game written in Go (with the amazing Pixel game library).

Game Design

Grid

The playing field is defined as a 2D grid. Monsters will walk on the grid, coming from left and trying to reach the right side.

Cells on the grid may be blocked, making it necessary for the fiend to find a way around the obstacle.

If the grid is completely blocked, the player looses all constructions (there must be at least one viable path for the enemies to reach their goal).

Towers

Towers are placed by the player via mouse interaction on the grid. Towers start shooting at fiends within their range automatically, favoring the closest fiend. A tower blocks one cell.

Fiends

Fiends spawn beyond the left limits of the screen and move (in waves) towards the right side of the screen. They try to find the shortest path possible and will follow it.

If there is no viable path, all monsters will die and the player looses all structures (this still rewards money and might be a valid strategy to rebuild the field).

Economy

The player gains money for each fiend killed before it passes the right limits of the screen. Towers (and other structure) cost money.
