I'm not one of the mods so not my place to say, but if she turns into a harpy and the parents also under go TFs, its probably at least in the spirit of things. It probably just got removed due to not being as obviously TF-themed and so got swept up in the broader purge of games that didn't seem to have been added to the jam for suspect reasons.
I'd probably just resubmit it and make sure to explain in the description what transformation elements are present in the game itself.
