Arrows aim. Hold SPACE to charge, let go to hit it. The power bar swings up and down — letting go at the right moment is the whole skill.
Up and down nudge your aim a tiny bit, for the fiddly ones.
One pool of strokes for the whole run. Every hole tops it up by its par plus two. Finish under par and you bank the difference. Run out and that's your lot.
Sand stops you dead. Water costs you a stroke and puts you back. Bumpers fire you off faster than you arrived. Striped walls move.
The holes never run out. Hole 4,000 is in there, waiting.
