how can i give him candy i cant do nothing
You shake the bucket by holding down and swiping left and right. A candy will appear, tap/click that. Check the hints for more info.
If it doesn’t let you shake, or the candy doesn’t appear, it might be bugged. My first mobile godot game and tested only on Chrome PC and Safari iPhone. If you wanna help let me know what exactly you can do, I guess tapping works since you see the character. And the system you are on.
