No idea on the flash vo thing I'm afraid there socheat, though I do wonder if this also means that the Ios version is inaccessible?
There is a new version of trials in tainted space that apparently works without flash, but sadly that's the game where the accessibility is still being worked on.
I do have some good news about the CoC revamp mod though.
The chief developer got back to me. It turns out the miner problem with adding access features is she/he has a hearing impairment so screen reader testing would be difficult. But the issue is being passed along to the dev team via discord and I sent link to Nvda in case any of their devs want to try testing things out.
Hopefully this means both games will have their buttons fixed in the future, in the mean time I'll try and give CoC a db page.
