I think your theme is nice and simple. The black text on a red background is a little difficult to read. I would've liked to move my camera around so I can see the enemies that were behind me. I also think the enemy patrol path is a little weird. I would also suggest making it possible to attack while moving so the player doesn't have to stop while walking. Some enemies also get stuck on the buildings. I would've liked some more direction on where I was supposed to go or what the item I was supposed to be looking for looked like.
