Okay, I finally decided to go with the project! My idea is to create a 2D platformer with XNA. As the the theme is evolution, I will be using some kind of evolutionary algorithms to change the main weapon of the character according to the usage. I can’t wait to see what happens with that one! 😀 Anyway, I first need to get all the basics working and then I will have time to concentrate on the real creation part
Yes! Finally cleaned the house and I am ready to start programming.
Downloaded the XNA Platformer 4.0 base from http://xbox.create.msdn.com/en-US/education/catalog/sample/platformer
Also, got the level editor from https://bitbucket.org/FinalMirage/xna-platformer-level-editor/wiki/Home
Thanks a lot for these valuable things. I can now concentrate on doing my own thing and getting things to roll on!

Okay, I am quite sure I will run out of time. This Ludum Dare I only have total of around 24h to work with. Thus, this is almost my last hour going. Here’s the screenshot so far. I am wondering, whether I manage to do the evolution part ready or not. Sad

Okay, the project is done now. Not the thing I wanted it to be, but working no matter what. The player character evolves to gain legs for jumping and a gun for shooting. Also added a level editor to the project, but didn’t have time to add more levels (due to a bug that appeared after last build). Anyway, it is up for testing. One day, I will finish it to be something better. Pretty good for a short 20 hour job 😉
