You know, it's really got to suck to be a customer these days. "Hello, I'd like to by this shield" "SCREW THAT, YOU'RE GOING TO WAR! Take this butter knife and begone!"
:(
"What's that? Aliens are invading? Better send the whole military to wander the streets and do nothing while we watch a giant arrow ram through the alien fleet"
The "restart with x skeletons" bonus is useless, seeing as how the game acts as if you bought them, and thus scales up the cost of additional skeletons, instead of having the skeleton bonus and the cost being as if you had 0 skeletons purchased.
Whenever you upgrade a weapon, it halves your attack speed until you refresh. And when you refresh, your exp bar goes back to 0 at that level, and all of your items in your inventory vanish.
it is a nice feature since you don't have to buy 20 in the beginning :)
