Hi! Did you try to set the "Fullscreen" checkbox in Settings to On, then click Apply, and restart the app? I can't replicate this bug on my device, fullscreen works okay there.
i couldn't find a way to...good game tho even with that mess- tho some screens like for instance the "fall damage" game over thing wouldn't work and seemingly auto-completed itself and stuck me in the screen..had to reset the game if i missed the rope thingy lmao but besides that it's good <3 do wish for more levels then 3 tho...unless i somehow missed something which i may have-
