Fughetta in d minor

I haven't posted anything in a long time so I figured I'd do so now. I don't have any way of turning the score into a pdf file and I don't have a midi so I don't expect many responses. This is a very short fugue (21 bars) in d minor using extended tonality and lot of chromaticism. The first four bars are more firmly in d minor, the next four transition to F major (though there is no cadence). An F major chord is never really heard although it is suggested in part by the theme. The theme is played in retrograde, in augmentation and slowly chromatically moves upward until it breaks into an episode based on the countertheme when the space between the countertheme diminishes in both hands and leads to a climax in a suggested a flat minor: F flat Major -> Eb major. From there, the music slinks downward until it reaches d minor for a short coda and a pretty standard cadence in d minor.
This doesn't follow all the rules of fugue writing. I tried to condense everything: the theme is one bar long and includes only 4 notes. The theme and countertheme are the backbone of the piece, it is played in augmentation, retrograde and in many different keys although it is mostly played in closely related keys to d minor: d minor, a minor, eb minor, F, Db Major etc. Hope you enjoy

alot of thing are going on at the same time,it may be hard to interpret the piece.
