Do I have to re-purchase the game for each new update if I want the new version?
No.
I only see up to .8c available for download(purchased previously). Is there some other way I need to access the new 0.9a download link?
So you paid not $10, but less.
You are correct. It was on sale for 50% off at the time.
Guess I better rebuy it at $10 for the update.
Perfect solution!
I initially purchased it for $5 then later for $10 (15 total now) & I am still unable to download 0.9
It's impossible. If you spent $10 - then you can download all files up to $10. It is important that it be $10 in one payment. Alas, that's how Itch works.
