There is English support via the English interface and English subtitles.

The translation is absolutely atrocious and feels like they got a five year old to proofread and quality check it. This patch fixes the script to be that of the one that was fan translated back in 2009 and significantly improves the enjoyment of the game. I don't recommend playing it without this. The official translation will sour your experience of the game. https://vndb.org/r109355 Just click the "Official Website" link and overwrite the files in the script folder with those.
