I've just finished the first act and... let's jus say I can't wait to get the second one. :-) Here's some feedback without spoiling too much of the story:
1) I've noticed some graphical glitches.
- When Vella climbs up the ladder to the blue birds nest, she somehow gets behind the ladder.
- When Valla climbs up/down to/from Cloud City, you don't always see the climbing animation as the screen fades too slow.
- In some situations, NPCs are still talking while no longer moving their mouths.
2) The game crashed once while walking to the pyramid. I've pasted the OS X crash report here:
3) On OS X when you play the game in fullscreen mode and try to minimize the game or switch to your desktop with a gesture, you can't always move the cursor when you get back to the game.
These are all the bugs I've noticed so far. I loved the graphics style was deeply impressed how smooth the game is running... even on older hardware. I liked the control style with the item menu at the bottom of the screen. However, I had to get used to it and intinctively tried playing in Full Throttle way (holding down the mouse button ti interact with objects).
Story-wise, I first thought that the first minutes of Shay's story (when he's sent to his "missions") were very boring. But when I noticed that they're intended to be boring to make you somehow connect to the character, I was fully on Shay's side and played it right through without switching to Vella until I had to. The story for both characters is very well written (props to Tim) and when the ending of Act 1 revealed how those two are connected... I was stunned. During the game I had several theories, but you guys proved me wrong every time.
But there are some negative points too... I thought the riddles are way too easy to solve (except the Prima Doom map thingy... that one confused me a bit). You practically run through the game and almost instantaneously know what you have to do. This is something that disturbs me while playing adventure games... when you just sit there and click things without having to use your brain. If it wasn't for the great story and humor, I would have quit playing after one hour.
In total: Great Job Double Fine!
One more thing... as I'm from Germany and don't own a credit card, I wasn't able to back the game on Kickstarter. Anyway... I made a pledge for the game though these forums and got my Backer access. Later, I bought a second copy of the game with the Double Fine Humble Bundle. When I backed the game I included a comment on what I need to do to get my name on the list of backers in the credits. Unfortunately, I never got a reply. I'd love to see my name there and be remembered as a part of this thing.
