Hi all,
I'm new here, so be gentle.

I've now played a little bit of Episode 01, enough to have a few thoughts and comments.
First, read a rather negative review here:
http://kotaku.com/5987760/a-fascinating-point+and+click-adventure-bogged-down-by-crapNow, I think that person was predisposed to dislike the game. I don't know why. Maybe someone stole his coffee that day.
But there are some valid nuggets in the review. Things I have noticed so far:
1) It does seem like it takes one more tap than it should to use Erica's abilities. But, honestly, that's a nit. You frown about it the first couple of times you do it, and then you forget it. It's not that big of a deal.
2) This image from the review does come up in the prologue. I think when she's getting ready to shoot the lock on the cemetery gates:

Note, that I did not notice the issues he describes when talking to Dr. Gallagher. I'm playing it on an iPad 3. I wonder if he's on a different model.
3) The transitions are slow at times. So slow that you tap to make Erica do something, and when nothing happens for a while, you wonder if you really did tap it. This doesn't occur all the time. Just frequently enough to interfere with gameplay. This is honestly my biggest concern so far. I'd spend some time looking into ways to speed that up.
4) Another nit, but I think the game is upside down. It appears not to use the accelerometer to determine orientation. I don't have a problem with that. There's no point in playing it in portrait mode anyway. But I traditionally hold my iPad with the volume rocker buttons on the upper left and the Home button on the right side. This is how it fits in my bluetooth keyboard as well. Cognition wants the Home button on the left and the volume rocker buttons on the bottom right. This makes it awkward to reach the volume controls. It also puts the speaker down on the bottom left, under my hand.
I feel silly even bringing up 4). It smells of user error, not developer. But I've tried quite a bit, and no matter what, I'm left holding my iPad the wrong way.
As for the good: it's an extremely engaging game and you can easily immerse yourself in Erica's world. I'm enjoying the heck out of it, and I finally have something I can do on my iPad in my downtime. Thank you so very much for that.
I'll have more as I progress through the game. I'm still not very far into it. Start of day 2, I think.
