Novashell is another 2D, cross-platform game creation software tool. Novashell supports only Linux, Windows and Mac OS X, not handheld platforms. It takes game creation one step forward from Game-editor and lets you work with more advanced features, such as advanced hierarchical goal based artificial intelligence (AI), physics, the option to connect an unlimited number of maps, warps, doors and passages, changing map dimensions during play, parallax scrolling with unlimited layers, mod support, particle system, advanced audio system with music cross fading, positional sounds, and, effect filtering, just to count a few. Of course, Novashell also has scripting support.
Novashell seems to be for intermediate to advanced users. This does not mean that the newcomers to the world of game creation cannot use it, but it is oriented towards the game creation enthusiasts. If you are a newcomer who can dedicate longer hours to learn the program and create your game world, then Novashell will be a very good fit for you.
