I give up.
I had to balance the game and resolve bugs sounds, and I would finish.
But I had a big bug that removed some of my code, and my last back-up dates back to before this part of the code ..
I don’t have time to fix all, I’m really tired (it’s midnight in France and I didn’t sleep during the weekend), and I discovered the game “Flooded Dungeons” (http://www.ludumdare.com/compo/2013/08/25/flooded-dungeons-almost-done/), it has a concept similar to my game, and it is much cleaner and attractive than my game.
So I give up, I’ll try again next time.
Good luck for people who are finishing their games, and good afternoon to those who have already finished! =)
