I'm really looking forward to seeing your IDE. In the meantime I recommend to use LunarEclipse http://sourceforge.net/projects/lunareclipse/. You can run the game, if you define an "external tool" which points to your love installation and as an argument you pass "${project_loc}"...

added one, too

This sounds really interesting.
If you really can add a posibility to debug the own game easier, this will be really great!

Can't wait for it
