This is the second post, the other one is under Hazel (it's the same user M. providing both very extensive and insightful feedback).

- (paraphrasing) frame rate slows to 2-3 fps with reshade on so I had to disable it

That's way slower than I thought it could get. What GPU are you using? In the final release will have two icons to click on, one that runs the game without reshade without having to use the Home key and click the 3 checkboxes

- the usage of shader effects doesn’t help while the game underneath is exhibiting traits which only exist in modern games. As an example, the way that characters move and how the scrolling is implemented is extremely smooth

I like that there's people who notice stuff like this lol. I totally agree, and the only reason I ended up accepting it is that once I disable it, it looks far, far worse than you'd expect, and distracting as hell. To the point you wouldn't want to have scrolling at all. I should record a video to show you, not sure if it will be represented correctly but with pixel by pixel scrolling it's just horrible. I went to see how Lucasfilm did it, they scrolled by multiple pixels, and it's even worse.  

- The change in the colours used for the under ground vs. the above ground parts of the game seemed quite large, but perhaps that helps to differentiate the two environments.

Not really, fundamentally it's the EGA palette. Unless I was to make all the screens dark blue (which doesn't work with the story as they have to be outdoors too) the color palette is just going to produce this vastly different effect. I am aware of it.

- I was stuck here for a while because I couldn’t find the ring, I’m honestly not sure how I managed to find it. It seems a very unfair first puzzle

Can you propose an alternative?

- The parts that felt the most awkward seemed to be where characters were speaking but the portrait graphics were not displayed, i.e. there is no visual indicator that two characters are talking, the only way you can tell that a conversation has ended is by waiting to see if more dialogue appears. It also felt a little strange that a conversation with another character can seemingly begin without the character portraits being shown, but then later the portraits will suddenly appear (I think talking to Dr Crowe in her office is an example of this).

I'm treating the portraits the same way a director would use close up shots. The portraits appearing in mid conversation are supposed to increase the intensity or closeness of the dialog. The mouth/head should be moving when portraits aren't displayed. Are you saying the mouth is not moving? If it does move that's how all the Lucas games worked. If it's not moving we have a problem :)

- The largest problems I had were around the logic for combining concepts to create new concepts. I like the idea in principal, but there are so many potential associations and links which could be made [...]

I think my main worry for developing Angelgaze into a larger game is that the same mechanic would exist in exactly the same form and become critically important to story progression

- I had similar issues when highlighting sections of the manual with the blue marker pen, I ended up clicking on everything because the correct sections didn’t seem particularly more relevant to incorrect sections, and it didn’t seem feasible to replay the slide deck to look for specific information.

Agreed here as well! It's tricky to really simulate the experience of searching, without making it seem arbitrary. How would you change it?

- My confusion increased when I accidentally found that I could highlight the telephone extensions list, but the game didn’t tell me to do that. Maybe I’m just not very smart, but I would be worried that these parts of the game are only working well for you because you wrote the solutions.

The idea was that you can highlight more things than are actually necessary. Without finding the 3 big things it won't let you progress. But everything else (extension numbers, alcohol/coffee etc) is optional.

- The only UI component which felt strange was scrolling text, such as when reading a concept that contains more than one page of text. Scrolling the text a page at a time probably makes it harder to read than scrolling a smaller portion of text.

So I tried line by line scrolling and it was even more confusing because characters appear to just flip like in the Matrix. What we have today is pixel scrolling that's what everyone's used to. I have to do more experiments with that TextMeshPro component and see if it can be done, I think the issue is that you then need another scrolling component on top of it - so far everything with UI and text has been an absolute nightmare in Unity... But I do see your point, I will take another look at some point.

- Having “Think” as a button in the UI feels strange because it doesn’t work the same way as any of the other buttons.

Agreed, I think the reason it's there is so you can go into the think screen from a dialog (when the lower verb buttons are hidden). Probably should just be text?

Thanks again for the comments! Everyone else welcome to chime in!
