Very nice golf game, probably one of the best here. The theme and additional mechanics make it stand out from most others, in a good way.
I only wish it was possible to repeat a hole later without having to restart the whole campaign, after my first playthrough I had 26 shots and a score of over 250k points, yet I had to redo it all just as good to spare 1-2 shots. If I could have just repeated hole 7 or 8, I would have finished that much faster.
As for the other medals, I managed to get them all after trying a few times. Escpecially the crocodile and secret area took me a good hour to do/find.
I can see that many others in the comment section have been asking about those and only a few gave a hint about the secret room, but nothing specific, and the crocodile medal wasn't answered at all.
So let me share my wisdom with you all, if you still struggle to get those 2 done.
Be aware that following a guide/reading spoilers takes away the fun and feeling of accomplishment of doing it yourself.
So here it goes:
SPOILERS
Secret area - in level 7 (cave with lava), shoot the ball into the light grey alcove north-west of the windmill to enter a room with many coins, which looked like a normal wall from outside.
Luckily (?) those coins don't count toward the medal for collecting all coins, probably because they are not in plain sight.
Crocodile saver - shoot the ball with full power through the tunnel, charge a second full shot while it flies and aim at the top plank of the bridge, where the croc is on. This should move the whole segment together with the croc a bit to the right. Now keep the ball with repeated small shots in midair and try to shoot it through the hole to the left with fully charged shots, it may break through without knocking the bridge over. This will take a few tries.
Be aware that running out of shots will result in the parrot carrying the ball to the exit, even if the bridge is still standing. This will NOT count as keeping the croc alive. Furthermore it will automatically finish the level, and since you can't go back, you'd have to restart the campaign all over again. So watch your shots, if you have only about 5 left, restart the level and try again.
SPOILER END
Have fun and don't give up immediately, succeeding in something by yourself is an achievement that nobody could take away from you. You may use this guide, but it will forever leave the reminder that you had to cheat on something that others achieved the honest way. A sour taste to your victory.
