Level editor:

Ok, seems we are getting somewhere, however I seem to be too lame to compile the luadec51 with modified lua-5.1 (damn, why those people can't add Makefile into the dist?)

Reason why I was not able to decompile the lua script first time, was because Rovio uses different version of lua that has default number type set to float instead of double. I was able to get over that and I attached the dissasembly of Level1.lua (unfortunately chunkspy lacks the ability to generate original structure of source code)

If someone can help push it to even more readable form, inform me.
