Nice game, but there seems to be a serious bug: at one point my attacks stopped doing any damage to the enemy, while he still could do damage. I kept playing for 20 rounds with no change. No type of attack was doing damage. This happened in the 5th battle or so. I'll let you know if it happens again.
I give it a 4. Not much of a challenge, but that may be just me being lucky :), but good for a first chapter. You woke the cat ;). Waiting for chapter 2
