This is the impossible game. The boss is 10e9 , or 1 billion (I think so) and you can do at most 4 damage each second and there is 2 boss The boss is shooting spreadshot Whats more , asteroid flow from every place (top , bottom , left , right) You won't probably win unless you have a very * 10 time

There are 2 modes:

Easy: You have the ability to do spreadshot and each bullet worth 2 damage
      Difficulty: 10 / 10 

      
Hard: You only fire straight bullet doing 1 damage
      Difficulty: 10e18 / 10 (harder than tidal wave)

Good luck with this sussy game.
