So off the rip "Over the top high energy reactions" and the like of comments made similar are subjective. This isnt my type of content however Its not difficult to give some meaningful feedback.
So during opening talking :10 - :14 the background music kind of bled in with your voice it was a little distracting for me.
Some nitpicking that probably isnt a huge issue but sometimes clicks from mouse are picked up.
Flow seems fine Im able to keep up with the story and you are talking the entire time vs people just staying quiet during gameplay so the action is kept up the entire time so thats a positive.
Entertaining is up to your potential audience but I would argue for people who like interactive/talkative creators then this is right up their alley. I think where this content could shine is potentially streaming playthroughs like this then chopping it up.
As far as losing interest for me personally you kept the same energy through out so thats a non issue. For me personally it might be "too long" I personally prefer like 20-45minute range for content but thats just my viewing interests. I do think maybe outside of diehard fans/audience sitting down for 1hour might be a hard ask but not impossible.
I do think a potential test you can do is this type of cut where small things are cut out(I assume) and you have the entire story start to finish and its all wrapped up.
The other test you could do is like a "super cut" where you chop maybe 20-50% of the "dull moments" not calling you or the content dull but in theme of keeping the same energy you presented during the intro there are some parts of the game that dont live up to that "hype" and thats to be expected in most games.
