just use a and d to move, and all you have to do on mobile is you just click the backdrop and it should follow you if not then i will add a draggable slider which might be easier (it can go anywhere and it should keep the rocket in place). though I unfortunately will have to shut down the game for updates. (also please dig into the files by clicking see inside there's a message for the people who play this.)
credits to anyone who plays this and support the game and my hard work I do on these games.
