I'm guessing most of the things that you weren't able to solve in this act will be confronted in the second one, like the snake for example! 8-bit mode is achieved by setting the game to the lowest resolution possible :)
Anyway, great way to end the game. I'm super-stoked to play the next part. The big reveal in the end really made me a bit shocked. I actually thought that it was the Dead Eye God that was Shay, but man, was I fooled! Do the have any connection though? He spoke about Project Dandelion.
And on the note of thinking that you're someone else. I thought it was really clever to portray "mom" as Vella as well, when you hear her talking about sacrificing. I'd think at this point that the computer and Merrick are both part of the problem, so to speak.
Well, I enjoyed it very much! Can't wait to see how they wrap it up.
