Dungeon versus Tower – from the start, the Tower has no chance of winning, unless the player is exceptionally skilled at playing as the Tower, or the opponent makes significant mistakes!
It will be difficult if you can't find the folder with Tactics, but otherwise – it depends on the initial setup (if you get a couple of good cons, like 1+2, for example, for the Miner and a quick rush, then GG is almost guaranteed).
I would also try playing against you with the Tower, although the chances are not that high...
