A well designed game, satisfying and addictive with it.
I've played for perhaps 10 hours and am only about halfway through. The tech trees are extensive and keep things progressing nicely.
The only suggestion I might have for the devs at this stage (but not a gripe) is that the colours and some of the 'buildings' are are just a little bland and it could be easier to differentiate between the various processing plants. It would be good to have something to make their product obvious at a glance perhaps. With that said, I didn't find it annoying as it is, I just feel it'd be more exciting to look at with slightly more distinct buildings. Perhaps some flashing pin-prick lights on the buildings or something might just bring it to life a bit more.
Thanks for a great game, impressive.
