I would agree with Dread. It is such a a nice clean game and that last boss was an actual challenge. Many games are awesome but fumble the last boss.
Before Dread, I would say the Super Metroid on SNES, that game introduced (at least me) the wall jumps and the sprint to down boost jump thing. I always tired to saved the animals when leaving the planet, but it’s not like they were able to get off the planet, so I’m not sure if it really helped.
Maybe make a version of the game when you aren’t a superhero and just the cleanup crew that has to fix the city afterwards. Sweep up the halls of Justice, and buff that coffee stain out of the table all without special effects.
