So, I have the original NES cartridge for this game as well as the Nintendo DS version. Ive played both numerous times throughout the years. Even though the game has dated mechanics and a very simple design, Ive always loved it and have a lot of nostalgia for it.
What works? I love the updated look, the updated music, the faster pace, even the controls I found intuitive. I was concerned how it would play on my iPhone 6. All of that was fine. The save features work well and the quick save is very nice.
What doesnt work? Well, everything. The game is buggy to the point of being nearly unplayable. The updated music that I enjoyed so much at the beginning no longer plays in any dungeon or on any screen. This is true even after closing the app. The game frequently freezes while completing regular tasks like opening a treasure chest or using a tent. There is no rhyme or reason and the glitches seem unavoidable. This would be a 4 or 5 for me if it actually worked.
Update: It does seem that the glitches have been resolved. The crashes and music issues have not been a problem. I have played this game on both the iPhone 6 and iPad Mini 2. I love the inclusion of the Dawn of Souls dungeons and the Labyrinth of Time from the 20th anniversary edition. It gives more postgame content. I also like the faster pace of play, particularly compared to the NES version. What I dont like... The difficulty. Theyve nerfed the difficulty to the point of being flat out easy. I also dont like that hits automatically redirect. That was part of the strategy taken away. Also, the leveling is wonky. Ill give it a 3/5 when all is said and done.
