No, I figured it out. Apparently this game isn't working with firefox and possibly other web browsers for some reason. I'm using chrome right now and it's working again :)
The flaw with the hard badge is that a random number of enemies spawn each day. I've only upgraded the rusty nail and artillery and twice I've been about 2000 short of the last repair.
This game is great, people need to stop spamming hateful comments. If you think this game is bad because you suck try Zelda 2. This game is pretty much a remake except every time you get hit in that game you lose experience and it takes much longer to get back to where you originally were after you die.
I lost every game except the one with the three bouncing green balls you can't touch before the 3X multiplier. I had an easy time with that game though and because it was the only game I had left it went continuously and got my multiplier to 7.6X for the easy and hard badge in one game. I recommend purposely losing every mini game besides that one for the hard badge :)
