for the love of god PLEASE reverse the arrow movement. I fucking love this game except there's never enough room on the screen to aim a shot. I don't know if you playtested this on a downloaded version or something, but the browser version's window is so tiny you barely get any power by pulling behind or below the ball.
2 easy fixes:
1. make the window a square, add blank space above and below the landscape window
2. reverse the way you shoot so you pull away from the ball in the direction you want it to go instead of the opposite direction, this is how pretty much every other mini-golf game i've seen does it.
Also, consider making a time attack mode with unlimited shots because I had a lot of fun just zooming around the maps spam clicking and wasting throws.
