Nice game, some problems though.
The game is quite fun. I thought the difficulty was just right UNTIL the boss at the end. His little axe wiggling attack makes him almost if not utterly impossible. Add the fact that he gets reinforcements and he becomes very frustrating.
All in all, tone down the boss a bit, add some upgrades, maybe a dagger to deal with those close up soldiers and the the game is perfect for what it is.
