This looks really nice and I would have no problem to pay 20 or 30 USD for the complete package, but besides the pinups for the 30 USD package and some features of the Custom Edition, neither here, nor on your own website are clear information on the difference between the old, the semi new and the new version of the game for potential customers.
You already showed of some of the crucial information at the beginning of this page, but the most important ones I think are those differences. And those I can't find. For example:
Are the visuals better in the new versions? did you make changes in the gameplay or are there more choices/paths or kind of trophies? did you alter some of the character designs and so on.. and even if you think as dev that it should be obvious that the main difference are the visuals (just a guess of mine), KNOWING them is a completely other thing. :)
It is easier to support a product or a dev, if you know such basic infos instead of just guessing them. Maybe I am at the minority here when I think that way, but I bet I am not the only one, and I think the most of those people just skipped the game or just played the free version, even if they would have contributed.
PS: I looked very closely but if there is an infobox or something that I missed that delivers the things I am searching for, ignore this post. BUT pls make sure that the info is better to find :P
