Evolute is a basic defence game in which you have to keep the enemy off but with added experience and skill system which makes the game rather unique. The current version will be the final version created by me but as the game is open source, anyone can continue the development.
The game is released under the GNU General Public License, so that anyone can freely distribute and develop the game further. The source code comes with both, the Windows and Linux versions.
Evolute is also available on SourceForge.
