the damage per second doesn't change when I upgrade my weapon. It would be also cool if you have an badge for the survival mode and a warning if an enemy fled.
Robot: "I became the best digging-robot in the world, I got the COre, but now I can't get rich. Just before starting my get-rich-mission my drill got stolen by a knight-like thief, talking about somthing like 'must save my princess' or so. Damn Knight." THAT would be a funny ending for the game. Alltogether a good game, but the people get too fast too greedy.
Lol. Found a way to kill the end Boss without walking through the labyrinth, without killing one other enemy and (possibly) without taking damage. Enter the labyrinth and obtain the gun. Then leave the labyrinth and go back where you came from. Then go down. After a while you'll reach the finish screen and you can enter the boss room. Kill him and you are the winner. After that you can kill the other enemys from the inside to the outside while some enemys are different.
some precious tips: 1) In level 28 you can drag the doors with the mouse (isn't showed in walkthrough) 2) to find the easteregg in lv.6, you have to type the elvish word for friend (MELLON).
