Very cool concept, not to mention the cool tech behind the game!

It was a bit hard to understand in the beginning, but it is quite interesting :)

Then I left the game for half an hour, and the robots did all the work for me (but the game started to lag) :o

I don't have a new enough ECL version to play this one, unfortunately.

Hey, I got the same libecl.so error as below, even though I do have ECL installed. I’ve tried compiling from source, unfortunately also to no avail:

It seems like installing ECL is not enough to run the binary, I'm trying the src way.
