the NSFW is a little bit of a joke, as a friend on discord wasn't keen on the fact the skirt flies up when you fall (so SFW just removes that sprite from the sequence)
The fans are mostly a nuisance as they catch your ribbons, and can throw you all over the place, but you can (once you get used to them) use them to your advantage... but I kind of ran out of time to put any form of level design around that.
Also glad I got in there early but I have already seen a couple of better transformation sequences so highly recommend The Forest's End and Mouline the Rouge if you want to see some more
