I have no idea how difficult it would be to code, but as far as controls go this game is very simple to play with touch controls. My laptop has a touchscreen and it makes hotswapping cameras a breeze.
I actually also used touchscreen in laptop for Foxy because it was faster to close doors using touch screen than reaching button with mouse xD However moving camera left/right is kinda PITA. That unfortunately implies that game would probably require mild rebalance for touch screens
