Thanks for the feedback. I was originally planning on showing the stats of units and stuff but I just ran out of time (and space on the screen). If I keep working on this that'll be something I prioritize. The wall is impassible until it gets destroyed :) Scavengers pick up gold off the battlefield and deliver it to the energy crystals (giving you gold to spend), and miners mine rocks and deliver stones to the crystals to give you stones to spend. It's definitely not well explained though. Thanks for playing!
