I need more time for the minigames. I can't heat the water for the sun-glasses-machine.
Five more seconds would be sufficient there.
I'm handicapped without any reflexes and I'm not the fastest either.
I tried Space/Enter, Enter/Enter (if you have a NUM-pad), but only get 4 of 5.

@fonzer:
Look for anything that looks out of place like not burning laterns, ivy on walls etc.
I have found many secrets but haven't been able to open all chests yet.
Look behind houses and trees, too, to find money bags.

Have you found the Spanish speaking bush near the Dragon Rider Village (next to the cave to Purapil)? Try it and look for the effects. Only one of the effects is really useful.
