Disappointingly easy

[loreangelicus]

GodClone, try for a game on impossible, no losses, at just 7 days.

The problem with an impossible run, even a no-loss one, is that you could map-kite, or at the very least you could essentially pick your fights from easiest to hardest. But if you add a time factor, especially something as restrictive as 7 days, then you are sometimes forced into fights that you would normally skip for later.

Granted, once you get to higher levels with a mage, you can just use a solo unit and take on enemies in whatever order, but the first few levels/islands would be hell.
