I am sooooo deja-vu'ing to Oregon Trail [722.2]
Dude.... your game's graphics totally take me back to the Oregon Trail days. Seriously... I love it. Great backgrounds... the road, trees, greenery, buildings.... it's the zenith of your flash.
Now, the gameplay.... OTOH... is a bit more... problematic. And when I say problematic, I mean overly simplistic. As others have said, a linear path with four stops along the way to kill enemies arranged in the exact same pattern... 4 each time (BTW, it's very considerate of them to line themselves up JUST PERFECT for your lance to slice 'n' dice 'em all like that!).... it's just not very full and enriching an experience. Even Oregon Trail had branches in the path where you had to select different routes or methods for crossing a river and so forth!
But here's the main problems I can spell out for you
A) the lance hit detection's a bit off... if you move the mouse faster than a snail, you can skip right past an enemy, even though the lance was flung right over them.
B) speaking of that... lances are used to knock people off a horse, and they're used along the same line as their length... meaning if anything, you would stab with them, not slice/chop.
C) you spelled Dulcinea right in the intro but wrong at the end of the gameplay.
But really, it's an educational and fun little thing here... you could really turn this into an awesome flash game on NG with just a little more work, man. Good luck tilting at windmills, Don Quixote style! #;-}>
