The first tiny update

Made a small update to the current build. Firstly, experimented with reducing the volume of the package, with more or less successful results (though, a more thorough pass is needed - however, I'm going to do it with a final  pre-Steam demo).

As for the actual changes:

1. Slightly tweaked enemy placement and amount on levels 1-3, to add a bit more spice.
2. Replaced the cutscene scenario so that the visuals were fitting the style chosen

Have fun shooting!
