Nice little game, especially for your first game! I think the game would be great with some more audio to reinforce what's happening on screen. Also, I think it's essential to have a visualiser that shows how far you've dragged, or maybe where your ball is going to go, something like you see a lot in golf games, which would make it a bit more clear that you're going to shoot. I'd also make it so the ball can't be shot from within the air, which makes it a bit harder. I'd also like to see some sort of visualiser where the hole is roughly going to be on a horizontal scale, maybe like an arrow at he bottom of the screen? Right now you kinda have to guess. Overall it's a nice game and you did a great job, nice one!
