Repairable bear traps
Make bear traps repairable after being stepped on instead of dissapearing because as it is they just seem a waste of valuable iron while just breaking it would take it out of play for the wave but wouldn't be such a draw on iron.
I like this! Perhaps to keep it from being overpowered, just increase the initial cost, then make repair free except for labor?
Your bricktrons can actually reset them. They only get destroyed if a Biftron or Warlock steps on them
I figured that out later
But thanks for pointing that out!
