What is it?

It's a terminal ascii game where you fly a ship through numbers. The goal is to shoot the numbers whose sum will be equal to the level's target. It's easy at the beginning, but higher levels have more and more numbers, and less and less space to navigate through them! The last level is level 12: I never reached it, but I hope somebody will :).

Demos

No walls, square world

Random walls, rectangular world

Configurability

The game can be configured in "world shape" (square, rectangle) and "kind of walls" (none, deterministic, random).

You can define your own keyboard mapping by modifying the 'eventFromKey' function defined here, the default mapping being:

• ship acceleration : 's' 'e' 'd' 'f'
• laser shots : 'j' 'i' 'k' 'l'

Supported Platforms / Terminals:

OS	Support
OS X	Yes
Linux	Yes
Windows	No (see this)

Your terminal window should have a dimension of at least {height = 42, width = 146}. If it is too small, the program will fail with the following error message:

From game thread:

Minimum terminal size : Window {height = 42, width = 146}.
Current terminal size : Window {height = 22, width = 165}.
The current terminal size doesn't match the minimum size,
please adjust your terminal size and restart the executable.

Delta rendering

The initial idea for delta rendering is based on code written by Rafael Ibraim
