I use the Magic Keyboard on iPad which makes it similar to a laptop. The game will just like all apps recognize the mouse pointer and various buttons and cards will react. However if then combining with the touch of the screen or simply waiting until the mouse disappears as the iPad is built to do, It will no longer come back. Usually in apps or in iPads homescreen the mouse pointer will be visible again by simply moving it. In Balatro however this doesn't happen and the mouse is no longer visible. It is still usable, just that you don't know where you are hovering and about to click. The cards will react on the invisible mouse though, as shown in the pictures. This is still active in 1.1.8
