The hard badge is hard..because it's just boring..., just try over again and again, It doens't really get harder and harder. But it's only a game for Levelers not for fun :)
You just need to play every level out (not in gold) and if you did them all.. You get a new item, Super Powerfull, and in every non-gold level you need to throw it one time, and you have gold ;)
for hell dining badge: buy the quaker and upgrade the damage and reload total, fully upgrade your wall, buy a lot repair man (20 or so) and a lot gunman, you only need to click your gunman will kill them and your repair man repar everything in an instant
