Hi all. Just want to share with you my little game hack. It's open source: https://github.com/ruskim/xonix Could be build for DS and Qt. DS build is attached. Actually it's a demo project for my students. It's purpose was to show them how to make simple games on Qt and explain how to separate game logic (engine) from graphical presentation. But for my fun I added DS support. I'll be happy if anybody find it useful.
