YMMV / Hydorah

• Awesome Music: Not only there's one of the best soundtracks in a free game in recent memory, with a couple even sung in reverse Spanish, but several tracks are not looping - they are as long as their respective stages are. Both the Original Soundtrack and some tracks rearranged by other musicians are available.
• Breather Level: Deep Space and Storm Eye. Lampshaded in the level description, which is "Upgrade your weapons"
• Demonic Spiders: The eels on the path of Path of Scylla, which will dash out of walls to bite and scare the crap out of you, eventually in large numbers.
• Sequel Difficulty Drop: Or rather, Remake Difficulty Drop. Super Hydorah has some elements that make it slightly easier than its original:
  • No Save-Game Limits anymore. The game autosaves after each level.
  • The shield powerup is more frequent and easier to get.
  • An "Easy" difficulty level.
• That One Level: Path of Scylla. Especially how the eels home at you at certain section of the game brings back some gamers memories of Gradius III's homing cubes... The game has branching paths making you able to avoid the stage, but completing the stage is necessary to unlock the good ending. Fortunately the boss is far less difficult and the boss fight has checkpoints.
