FlightThrill is a console game based on an existing online Java game "Fly The Copter", where you navigate a helicopter through a rough terrain and avoid collision. It is based on the ncurses library and supports loadable terrains that you and your friends can create yourselves and challenge each other.
Go to the project page and download both the game and the terrains. You cannot play without the terrains.
You do not have to compile the game if you're using a i386 or higher processor—just download the "static" binaries.
If you want to compile it yourself, be aware that this game does not have a `configure` script—I don't know how to make one. The Makefile that comes with the game is successful on most machines, including x86 Linux 2.6, AMD Linux 2.4, and Alpha Linux 2.2.
