Thank you for your feedback.
I didn't put any info on how to exit the bridge building mode because I assumed people would try clicking Escape. I realize now that it may not be that obvious to a lot of players. Maybe I should just not allow bridges to be deployed if the player has no resources.
Art is not my strong suit but I did actually try. Unfortunately this is the best I can do in this much time. I'll definitely try to improve my art skills next.
I think the resource confusion was in part caused due to a bug where the crafting menu would not show up. That is now fixed. So if you can, please give my game another try.
Once again, thank you very much for your criticism.
