I liked this game, but I'd like to adjust the difficulty curve. At several first tiles, a player might need 2 balls to reach the golfpost, and he will lose if the first ball fall. Probably it makes sense to provide the first additional ball earlier.
Yea the randomness can be brutal... in a full game there should probably be more ball rewards early and then less later, but currently its just a new ball every 6 rounds
