I don't know if you are aware of this, but your game is seriously lacking keyboard shortcuts to improve accessibility for people with physical disabilities. This is especially true on the course where the drag and drop function is the only means of adjusting the shot spin and the target flag. I personally have been struggling with this for a long time, quite frustratingly I might add. Please add the following keyboard shortcuts:
1) click anywhere on the ball at the bottom right of the screen to activate the spin function, which can then be adjusted by using the up or down directional key on the bottom right of the keyboard.
2) click anywhere on the target flag to activate the location adjustment function, which can then be adjusted by using the directional keys on the bottom right of the keyboard. For big adjustments, use a combination of shift + whatever directional key is relevant.
