i mean't rather than touching (for example the start button) i drag a mouse cursor to the start button then touch the screen to click it
That's a rather weird way to control it lol. We support either mouse, or touch, no in-between shit like this. If you really want to be a masochist, then I suggest you try running Windows version of FloppyScryption in Winlator, IIRC the game functions fine in there, and Winlator has mouse working this way. Though at this point you might as well just run the original game in there XD
