You can’t see the sidebar? Wide screen mode will not fix that, all it does is remove the width constraints on text. It’s not like a landscape mode. You should be able to open the sidebar by tapping the menu button on the top left of the screen.
There are also no other drop-down inputs anywhere else in the game. It’s only supposed to snap on the “change” event, your browser is emitting that event on “input”, which is wrong, but browsers emitting the wrong events at the wrong times is not that unusual. In other words, this should only happen in the settings menu anyway, since in other cases, it wouldn’t be a big deal if both events are triggered at the same time. I should note this is not normal chrome behavior, so I need to investigate.
Also you can manual save at any time. Turning off auto-saving is not necessary to prevent soft-lock.
Edit: How to access the menu is explained during the in-game tutorial, immediately after the first sex scene. I feel like the hamburger icon is nearly universal for menus but I guess I can move that even further up and put it on the first screen of the game.
