Thanks a lot :) Ah yes, the iron ore is a bit hidden, but the map isn't random, so failing on the first try and remembering where the vital resources are for the second attempts is part of the difficulty (at least in this demo, since the maximum playtime is maybe 10-15min).

Thanks :) Interesting, I know you can click resources in the darkness (too little time to implement a check there XD), but allocating workers shouldn't work without a valid light source around (i.e. they will get deallocated immediately with no resource gain). As for knowing what can be harvested... basically everthing that is not a barren tree is a resource :)
