Mysterious Saucer Stage Issues
This is where it just starts to get stupid.
Too much thinking here...
Once again there is no need for complex puzzles in a Mega Man game. You have to know how the Mega Man jump dynamics work precisely here to not set off the alarms. No other Mega Man game relied on this. It's just not fun.
Same thing here... too much reliance on Roll's special ability.
And here as well...
And here as well... You have two choices, get hit and let the 3-second invincibility get you through these parts or precisely double jump at the right moment.
The slide and jump BS
There is a little-known feature that is mostly used in Mega Man Maker levels where you can get a jump out of a slide. Well, here you basically have to do it if you don't want to get hit. This should not be a requirement to play a Mega Man game.
Boss confusing dynamics
How to fight this boss is confusing if you don't watch someone's video on YouTube. As a player, I didn't know you could go back into the pit to switch between Rock and Roll. I think the biggest problem I have with the game is I don't like playing as Roll. Her character design and abilities are weak.
