Oh gods. VVVVVV's core mechanic is that you don't so much "jump" as you just flip gravity, and you only get to do so when your feet are firmly on the floor. This leads to some very interesting designs. The stage "Veni Vidi Vici (Doing Things The Hard Way)" is possibly the evilest level I've ever completed in a video game. Just a tiny little block, trivial to jump over, but the lack of a jump button means you have to.…
That was the case for me too, until I recently picked up the game Celeste. Some of the C-sides were so evil I just gave up and never beat them (I have a wife and kids, time is limited). This is coming from someone who generally likes hard games (big fan of Dark Souls series, for example, and yes, I know "hard" is relative).
The Celeste Chapter 9 golden strawberry though... that has got to be the most evil collectible I've ever seen included in a mainstream game. I would bet To put it in perspective - to earn a golden strawberry you must beat the level without dying once. If you die, you are sent all the way back to the beginning. This isn't too hard if the level only takes 10 minutes to beat like Chapter 1. However, Chapter 9 took me over 4 hours to beat and I died over 1,000 times. And not only that, if you manage to beat Chapter 9 without dying, you are transported to a secret extra level (that you've never had a chance to practice). You have one chance to beat the secret extra level without dying - only then does the game award the golden strawberry.
I can't even fathom the amount of time and practice required to accomplish this feat. It must be up there with some of those insane Mario Maker levels.
