You can go to the final level by keep going backward from beginning. This reminds me the Oroboros. I wonder does our universe loop infinitely like this?
The UI of level select screen sucks too bad. Why do I need "next battle" and "previous battle" button to choose levels? Why not list all the levels on the map?
The trophy system is quite confusing. You get trophies either by earning achievements or by beat levels speedy, while only the latter ones could be used to buy items in trophy store, what the hell?
TIP: after opening the door, if you found it's harder to reach the exit than to reach the entrance, you can go back to the previous room, the door will remain opening when you come back!
For the hard badge, after you complete day 2, backup your savefile. The savefile is in a folder called "EarnToDie_NotDoppler_viral.swf" , do a search. If you don't achieve the badge in day 3, restore the savefile and refresh the page.
Don't waste clubs! They are essential for the last two levels. If you collect all (2 to 9) of them, backup your savefile. (the file is in a folder called "Fairway2TinyDemo.swf", run a search) Then try to get 3 stars by using clubs in later holes, if you didn't get 3 stars, restore the savefile and refresh the website to get the clubs back.
