Frustrating
I was exciting when I started playing, but the glitches and technical difficulties got in the way. It's close to being an excellent game, but it fails badly in a couple of the most important areas.
When I started playing, you a wonderful introduction on how to play the game. But it left out all of the keyboard functions! I was constantly getting defeated by enemies of screen simply because your walkthrough was missing a few frames. It's a small lack of polish, but it's in an extremely vital area. Your audience needs to know how to play the game to enjoy it.
Then there's the controls. Without the keyboard functions it's extremely difficult to pick up the dragonpoo, and nearly impossible to do in time. Again, a minor issue with a very important element of interacting with the game.
The rest of the problem was just the random glitches. Sometimes my knight/archer wouldn't show up for a battle. One time after a boss battle, the music (and sfx) wouldn't stop looping. Boy that made me want to keep playing.
Fix the glitches and the small stuff and this will easily be in the 8 or 9 range.
