Rating for play on iPhone: Impossible, don’t bother.
This game is probably great on a larger device, but the controls are impossible to use on iPhone.
First, they are clearly still designed for a cursor, so the UI elements respond to hovers, not swipes.
For example: to open the inventory, you have to pretend to move a cursor from the main screen to the right margin and stop (“hover”) on the inventory, which then opens out into the main screen. That makes sense if you’re using a cursor. But on a touchscreen, that’s equivalent to swiping right on an element that opens to the left. To close it, you move the pretend cursor back to the main screen, essentially swiping left on an element that closes to the right.
Second, the targets are still sized for a tiny arrow, not a thumb. I understand why: the art is so detailed that a target big enough for a thumb could activate three or four objects. Fair. But frustrating.
And speaking of detailed art — make no mistake, this is a hidden object game, at least on an iPhone. It is almost impossible to see functional elements like doorbells and latches, much less the objects hidden inside.
I’m sure this would be a fun game on a bigger screen. I just wish I had known it was impossible to play on an iPhone before I spent money on it.
