cel7
A downloadable framework for Windows and Linux
cel7 is a 60kb framework for making grid-based games limited to 4-bit color ASCII output. The framework is based around the fe programming language.
To run a game simply pass the game's code file(s) as a command-line argument or drag a game file onto the executable. Your game file(s) can be appended to the end of the executable to create a self-contained single-file game.
