I played through the the first palace and started into the second palace so I can’t comment on the later portions of the game but so far I have these observations:

Pro: The game has innovative level design and the changes to the world map add an interesting twist. I appreciated the required use of jump to reach the boss for palace one which forces you to fight with jump active. Very cool.

Con: The difficulty level especially in the early game is very unbalanced. There are no roads so expect to get attacked frequently and see enemies that are normally not encountered until the halfway point of the original. There are enemies placed so that you can’t proceed without killing them however this requires a ranged attack so you are required to clear out the room and then kill yourself so that you restart with full health. The cave containing the trophy for example.

Final impression: I like the this hack but it needs a balance update. The write up claims that no grinding is required but this is not accurate. It feels like you start at the second half of Zelda 2 without any of the upgrades.
