Accessibility has gotten worse

The icon finally changed to match dark mode which is good, but the tutorial is blinding white (no dark mode) and you can't skip it. They went backwards in being dark mode friendly. Furthermore the bright white flashes are still there when the app starts. I can't play the app anymore because it causes problems for my eyes.

Edit: as a response to the developers, "a minute or two" is a dismissive way to view a massive problem to someone who has a disability. It seems small to you, but maybe if you had that problem you would not see it that way. That causes people pain and it's hard to see screens in general when you are light sensitive. I cannot show you the flash because I cannot get past the view screen to show it. Chances are if I showed it to you would think it is a minor problem too as the above, so why go to that much work and pain.

To others who actually care about disability and accessibility, this developer's response is telling. Don't bother with them or their app.

Response from developer

Thank you for your review, and we are sorry for the problem this causes your eyes. You are right about the intro. It uses the light theme, whatever theme you set in the app, and the Skip button appears only on its last screen. We will look into it. The intro is a one-time screen of a minute or two, and it does not return after you pass it once. The rest of the app follows your choice under 'Settings' => 'Theme'. About the bright flash when the app starts, please send a short screen recording to support@logic-wiz.com. It shows us which screen flashes, and we can then look at it.

Love this app!

My favorite game, especially on long plane rides! I can pass hours with these puzzles and all the fun variants. Plus it’s better for my brain than other games :)

Neues Update

Ich liebe diese Sudoku App eigentlich, seit dem neuen Update ist aber das Interface katastrophal. Die Legacy Tastatur funktion ist auch nicht das gleiche und wirkt viel umständlicher als es war. Bitte macht diese Änderungen wieder Rückgängig.

Response from developer

Thank you for your feedback. You can return to a puzzle interface similar to the old UI with 2 steps: 1. Turn On: 'Game Settings' => 'Legacy Keypad'. 2. Turn OFF: 'Game Settings' => 'Show Keypad Tabs'. Please make sure that you do both steps. If something still feels harder than it was, please tell us what at support@logic-wiz.com, so we can look into it.

Yup

Great tools for solving, easy app to use

Überragend

Das beste Spiel, dass ich seit Ghostbusters (C64) gespielt habe.
