Hi everyone,
This past couple of months, we've been doing significant engine enhancements with a port to Direct X.
We hope to support more lower-end computers and port to new platforms. The latest versions use only half the memory of the predecessor.
Since 2013, we had been using SFML libraries to connect to OpenGL and Open Audio. The new port to MonoGame is what directly supports Direct X (both are available in the launch options).
We anticipate having Ports for Mac and Linux ready for you very soon.
