Controls for Andriod

Good Day

As per the subject, I made a game & is fully working on PC but when i converted the game, it launches but there are no controls on Android.

Kindly advise how to incorporate the controls so it can work with android as well as i want to add three buttons only
(move left, move right, jump)

Also when I tested the game all of the assets have lost their color, why did this happen.

Thanks

I solved the controls problem, the platformer template had the solution to it.

but the biggest problem is the graphics issue, specifically anything that was defined as “TILED SPRITE” isnt being viewd properly and is glitched
note: even the gdeveloper platformer template had the same problem when exported to android using Intel XDK
photo of the glitch attached.
