Save the Earth!

I've been trying to get to thecode of this game to do some spreadsheets and some calculations but i have slight problem with it. I always thought that the main code is in Assembly-CSSharp.dll but as you can see

That file has only 21kb. I opened it and there is nothing in there. I tried the biggest file as well but its basically full of generic Unity stuff. Can unity games use some other source of code to work? like js or smth? If yes how can i get to it? Thanks in advance.

PS. Is it normal for some files to be detected 2 times?

PSS. Link to the game if anyone is interested. http://www.savetheearth.es/

Use a proxy or network sniffer to see all the files it loads.
Can't try the game myself as the fricken unity devs cut support for my CPUs long ago... they compile for ARM, but are lazy to build a non-SSE2 player for x86?! damn bastards...
 

I have no idea how to do it. I can see in wireshark that some js files are being loaded but how can i get to them?

EDIT: I just grabbed the unity3d file and unpacked it. Contained some files that werent detected by the dumper. Now i believe I have file i needed.
