With our new achievements system, a classic mode has been discussed as an unlockable option. Which would feature lttp style Link and tiles, with no filters. So that may be a possibility, although it's not concrete. Honestly, the FSA style looks weird without the filters though.
The achievement ideas are going to be pretty cool. There also may be a contest with the first release of the demo. The top five achievement points holders would get a prize of some sort. No clue what the prizes should be at the moment. People would have to register here for the opportunity to win. Use their ZFGC account name as the identifier.
