That could be a bug with the Itch app if *nothing* is happening... but I have one more idea to try: Right click on the Version number in the Itch app (right above the "Check for Updates" button...
->
Advanced -> Revert to Version -> Select the top one in the list,
should read something like "#30996 - 23 May, 2017..." (that's the latest 0.35 one).
After
you click it, it'll close the popup window and you should see the game
start downloading. Then try launching again when it's done.
So the other behavior you noticed (Clicking the "Update Available" button from within the game, and being shown a browser page to buy the game again) ... is probably just because you're not logged into itch.io in that particular browser. On one of my computers, using that button always opens Chrome for me, even though my default browser is Firefox.
Sorry this has been such a pain. Not really sure whats going on.
Where did you suddenly get the 0.32.1 version? that's way older...
