This is the first quest (I think) with two separate classes (back in 2007), which is why the title is Link's Decision. About a third of the way through the game, you choose to be either a knight or a wizard. Originally started in v1.92, this quest predates all the options in Zelda Classic that allow for multiple character classes, stat modifications, and difficulty levels. Instead of any of that, some items were assigned as class items. Each of the class items can only be obtained by one of the classes, providing for a very distinct split in abilities and play style.

There are six class dungeons, but only three can be accessed by each class. There are also differences for the classes in two of the triforce dungeons. Both paths are pretty well balanced, with their advantages and disadvantages. I would say the knight is a little easier.
Aside from that, it is a pretty straightforward quest with lots of dungeons. The path of the eight triforce dungeons is spelled out as you proceed through the game, but until the sixth dungeon it doesn't have to be so linear. Aside from the three class dungeons you'll be able to enter, there are also three optional dungeons either class can enter. They have difficult challenges, but useful (and honestly sometimes necessary) rewards. That means each playthrough has 15 dungeons.

There is just one overworld screen (much smaller than my other two quests). It's divided into twelve districts. There are no labels, but each district has its own music, and usually the biome changes too. The whistle whirlwind works like usual, but there are also two 3-stair warp rings. All the secrets are marked.

This quest uses old 8-bit graphics, with some custom made tiles. It has a lot of custom music (midi) too, 49 songs. To match the graphics, every song is from an NES game. I figured before I release a fixed version, I'll make it so you aren't endlessly hearing the same song every dungeon. You hear every song, regardless of the class choice.

Try both classes. They really are very different from level 4 onward.

Story is pretty simple. Ganon kidnaps Zelda, Link must go find Zelda. First he has to collect the triforce pieces that have been scattered to keep them out of Ganon's reach. That's all, so this is much like the old NES game. The sequel actually has a story, if that's the kind of thing you need.

Write down the few maze paths that are in the game. You may want to write down other things as well, as certain hints will only be given once (ie there is an item in the room).

Choose your class before reaching Lvl 4. The two caves are very close to each other, right after you get through the maze path. The knight is good at fighting, and the wizard is good at magic, so that's how the class items are divided up.

Go for the first optional dungeon after beating Lvl 4 in order to open up the path to the town. You can buy all sorts of useful items there.

Later in the game, there is a single superbomb. Use it in the right place (it was obvious earlier in the game) and you can get basically infinite coins. Great for buying everything.

Complete walkthrough is right here (and linked in the readme). Every secret, every map, every list.
