- Broken Base: Most player reviews either hail this as a masterpiece or consider it a prime example of how not to create a good challenge quest. Generally, the positive reviews focus on the item balancing, combat, music choices, and dungeon design, whereas the negative ones focus on the palettes, encouraged reliance on pots for healing, handling of difficulty settings, near-impossibility without all optional upgrades.
- The dungeons in general. Most players find them among either the best or the worst ever made in Zelda Classic; they're frequently praised for their difficulty and unique enemies (especially the bosses), but criticized for their palettes, Schizophrenic Difficulty, and general pattern of "clear a few rooms, return to entrance, break pots to heal, repeat".
- Venser's Cane. The most powerful weapon in the game, and makes quick work of anything that isn't the Final Boss or a Bonus Boss.
- The reward from each Bonus Boss makes the other significantly easier. Sasic gives you a ring that greatly boosts your magic regeneration, and Tartaros gives you one that rapidly regenerates your Hearts.
- Goddamned Boss:
- Before the 12/20/15 update, Scourge was this due to being hard to hit properly. It needs to be hit in the back, but it moves randomly when it's not attacking, and it always turns to face Link when it is. To make matters worse, bombs *sound* like they deal damage, but they don't actually harm it. The update nerfed it by making it pause for a second or two after each attack. Word of God is that the pre-nerf version was the result of a code typo.
- Sasic is this to most players who find him easier than Tartaros, largely due to his ability to heal - and your inability to stop him if it was triggered by you doing the same.
- Heartwarming Moments: Bringing the Yoshi Doll to the mother and child in Southern Remdra. The mother is incredibly relieved to know that her husband is still alive, even if he can't escape Northern Remdra yet.
- It Was His Sled: The Big Bad's identity (Venser) is this within the Zelda Classic community, largely due to his notoriously difficult boss fights.
- That One Boss:
- Medusa is probably the most common point at which Hero Mode players give up or switch to Normal, due to her incredible speed, ability to curse Link with most of her attacks, and invincibility that must be lifted with light from the Mirror Shield at regular intervals.
- For those who make it past her, Lumen puts up another tough fight in the Starlit Temple, especially against those who don't realize the Portal Sphere can cancel out Venser's residual power.
- That One Level: The Seaside Ruins. Even most of the quest's fans agree that its out-of-place difficulty is one of the quest's weaker points. Partially addressed in an update by reducing the damage dealt by its most common enemies.
