Clever game ! I enjoyed it. Slight bug (or is it a feature I didn't understand ?) in which sometimes you just can't create connections anymore (the link appears but disappear when you click the second point)
Thanks for the feedback! I haven't seen that one, I left a (not very efficient) visual cue indicating whether it was possible to build a link, if the link is larger than 5 units, the color turns... some transparent gray-ish, not sure it was the case, did the link remain blue-ish before building?
