is it just me?

[flamethrower]

hello everyone,

i'm new to this forum (and tear-down) and i have a couple of questions.

1st:
how do you undo moves?

2nd:
is it just me or is this game nigh impossible to get past "songs of destruction"? i have tried it soooooo many times and have come close but always seem to get swamped by aliens.

is there a way to adjust the difficulty? i'm playing the latest version V1.021

There are just far too many aliens to handle.

p.s. i used to play space hulk the board game and i dont remember it being this difficult.
