i tried the free trial of 'Sorry We're Closed' and it has limited M&K support, the vertical view when you go in first person is inverted and i wasnt able to fix that, the keys shown are the controller's only and the mouse cursor only shows on the menu.

'Techtonica' has limited M&K support, mouse cursor doesnt seem to work on the UI but they do when looking around, no keybindings customization and you have to invert Y axis since its invented for the mouse by default, you're only told the controllers keys to press so for M&K you kinda have to guess what to click, and there's also some sort of mouse smoothing that you cant disable and it's kinda annoying.

'A.I.L.A' has limited M&K support, invisible mouse cursor, no keybind and mouse sensitivity customization and the game only shows the controller's keys to press, but the rest works fine.

'ROUTINE', new on gamepass, has full M&K support, with keybind customization and everything.

'Voidtrain' has M&K support but mouse cursor is Invisible and you can't customize the keybinds plus you kinda have to guess what to click since it shows both the controller and the keyboard's keys, its playable but definitely needs an update.

@RIOO5047 I would have to buy the game to know that but considering i can't find anyone online mentioning it having M&K support i guess it's safe to assume it currently doesn't have.

'BALL x PIT' has M&K support.

'Deep Rock Galactic: Survivor' that has just arrived on GamePass has M&K support but you can't customize your keybinds and the mouse cursor is invisible.
Edit: During gamemplay you're really only going to use WASD so not being able to customize keybinds really isn't an issue, invisible cursor is a bit annoying though.

Great news for Ready or Not, the game got updated today and now you can customize your keybindings and mouse sensitivity on consoles, plus a lot of issues within the game got fixed.

'I Am Your Beast' has limited M&K support, first you have to go to the settings using a controller and on camera settings invert the Y axis and then you can play, cursor is invisible and you cant customize the keys, other than that it works fine.

@Arturllm Yep they did, i was going to buy mostly because it was going to have M&K support, i kinda lost interest now.

'Grounded 2' has full M&K support

Just tried 'Tainted Grail: The Fall of Avalon DEMO' and it has limited M&K support so i assume the full game does too. Keybinds cant be customized and any menu navigation doesn't work with the mouse, also, you need to invert the camera on the game settings because the Y axis is inverted for the mouse.
Edit: Combat with the mouse is not possible, you can aim and look but mouse buttons do nothing.

'Mecha BREAK' has full M&K support, no keybind customization for keyboard though.

'Crime Scene Cleaner' has M&K support but mouse cursor is invisible and the Y axis is inverted for some reason(only mouse, not controller), you have to invert it on the Accessibility options which will then fix it.

'FBC: Firebreak' has full M&K support and you can also customize the keybinds, also 'Still Wakes the Deep' M&K support is limited since the mouse cursor is invisible.

'The Alters' has M&K support but keybinds can't be customized and the mouse cursor is invisible.

'Clair Obscur: Expedition 33' has M&K support, unfortunately the game doesn't tell you the keybinds and you cant customize them but they still work.
