In the tutorial level I keep dying by the time I get to the archer. What are some ways that I can keep myself alive?
Always use the "Attack-Step Backward-Step Forward-Attack" technique.
So advance toward the enemy, give a hit or two, then quickly step backwards in case he gives you a hit.
For the archer, he's stucked behind the tables, so you can use this technique with more ease.
And don't be afraid of sleeping in the dungeon. Save before, in case you get attacked in your sleep.
