I really liked this game. Great puzzles and atmosphere, and of course, cute bunnies that you save with hat magic. I appreciated how much you paid attention to the little stuff like how easy it was to keep track of what you had found, and where you found it, so you knew where to look for the stuff that you hadn't. Those sort of affordances are so useful in a game about collecting things from all over a world map, so please keep them in!
Regarding the name change, it does bother me when a series has two entries with the same name, but it makes total sense if this is going to be the game that really reaches out to a bigger audience to have the snappiest and most marketable name, and Witchway is a pretty snappy and marketable name. I can forgive it of a tiny indie much more than I can, say, Electronic Arts or Square Enix!
On the other hand, 'Witchway Deluxe' kind of gives the impression of additional value, like a premium product. Maybe that would be more enticing to potential customers? I don't know!
