The artwork was brilliant, and the soundtrack, although a little repetetive, was quite fitting.
The abrupt ending really hurts the game, as does the lack of structure to the quest.
There should not be purchasable items that do nothing, particularly with a finite amount of in-gam money. The last thing you want is a player getting stuck with no means to progress.
And overall, this felt unfinished. THe player is fooled in to believing that there is more than one way to complete the game, implied through the clocks, the postcard etcetera, when in actuality there is not.
Regardless, looking forward to future additions to the series.
