Tips on playing on mobile?

My laptop died a year and a half ago, so I can't play there. I've tried the mobile version but my screen is far too small and the controls are too much for me. I tried playing with a controller on my phone, but even though that works in the launcher, once you're in the game, no dice.

I really want to play but I dont know what to do :( i tried sending an email but haven't heard back and its been months.
