These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: Gameboy soundtracks never sounded more exciting than this.
Player Punch: For a monochrome 8-bit game, it's positively brutal. A quick rundown:
You lose your best friend, Willy, right off the bat after he gets mortally wounded in a gladiator match.
You meet the girl when her sworn protector dies.
The unnamed town greeter NPC for Wendel is backstabbed and is never seen wandering the streets again. Forgot him, didn't ya?
When you go to rescue the girl from the Dark Lord, you fail because Julius uses the opportunity to kidnap her and ascend to the land of Mana.
When you help Amanda get the curse cure for her brother, a medusa's tears, there are none... but Amanda undergoes a Body Horror, and begins to mutate into one herself. She begs you to kill her and take her tears before she can no longer control herself.
When you complete scaling the Tower of Dime (the alternate way to reach the land of Mana), Robot Buddy Marcie offers to throw you to safety after the Load-Bearing Boss dies. Once you do, Marcie reveals that it lied and is unable to jump after you - it knew that if you knew it couldn't, you'd waste time trying to save it and you'd have both died.
Finally, when you finally defeat Julius, you find out that he drained all the Mana Tree's energy, destroying it. The girl has no choice but to become the Gemma, the new sprout of the Mana Tree, and you're left alone, becoming the newest Gemma Knight to protect her. What's worse is that she had no children, meaning that when she eventually falls, the Mana lineage will end and the world will be fucked.
