Hi. i have some advice on some stuff like when u destroy upgraded building u sould destroj onli 1 lvl of it end get some recorces back from that u had to use for upgrading. so for each lvl destrojd to get back somethin rether yust 5% of original building.
in storige there should be nice to see some arrow beside the supli like water up for if u are gaining recorces(green) or losing them down arrow(red)
