Hai!
I’m in! This is my first ludum dare entry and I’m really excited
! I will be using C# + XNA and I will be using a small base engine ( http://dl.dropbox.com/u/74691045/LD23.rar ). Nothing fancy, basic screen management and some kind of entity-component system. Anyways, I’m gonna go sleep now so that I won’t be tired when the competition starts 
Good luck to everyone!
