I will reserve my detailed thoughts for a full review once I finish the episode, but, I must say, having played through the prologue and a bit of the main narrative so far, the one thing that irks me the most is actually the controls. And believe me, I was prepared to HATE on the dialog, which hasn't really been too bad, outside of a few forced sounding lines and an overuse of expletives.

Obviously point-and-click works fine here, but the controls feel like they could have used a few more passes to streamline the AMOUNT of clicking and mouse movements you actually need to do to perform any one action within the game. I'm not sure if it's any different on PC, but playing on a Mac it feels like I am constantly dragging my mouse all the way across the screen to click things, be it the inventory, cognition icon, etc., and then dragging my mouse ALL THE WAY back to the hotspot, clicking again to bring up the action icons, accidentally mousing off of the icons so they disappear, having to click AGAIN (#@%$!!!) to bring them back, etc, etc, etc. It's not terrible, but a click-hold-release system similar to Full Throttle or Curse of Monkey Island would have been MUCH more intuitive and improved the flow of gameplay. As long as you're holding the mouse button, action icons would stay visible. Move the cursor over the chosen icon, then release the mouse button to select it. No fuss, no muss.
Even worse is the amount of unnecessary mouse-dragging and clicks necessary to perform cognition abilities on an object. So first, I have to drag my mouse down to the corner and click the Cognition icon, then I have to drag my mouse all the way to the hotspot and click again, THEN I HAVE TO DRAG MY @#$%^&* MOUSE BACK TO THE GOD-DAMNED CORNER AGAIN TO ACTUALLY ACTIVATE THE ABILITY?!
YAAAAARRRRRRRRRRRRGGGGGGGHHHHHH!!!!!!!!
Why?? Obviously if I turned the cognition power on, I want to use it on the hotspot! Why the extra step of dragging back to the corner to click the eye?? And if there are multiple abilities that eventually get learned or whatever, why not just use a similar action icon wheel like for normal interactions so I don't have to drag my mouse away again? It just feels clunky and bogs down the actual action of playing the game.
Anyway, I really do mean this little critique constructively, even though I'm jokingly exaggerating my irritation level.

I'm enjoying the game so far, but the controls do feel a bit unrefined. It seems like some streamlining could make the whole experience a bit tighter, and wouldn't be too hard to pull off. Then again, I know nothing about the engine you're using, so it might be something totally beyond the realm of possibility.
