Bugs:

Unable to see cursor on meatworld.

Unable to give a rating for completed levels.

During Super Potato Boy levels I right click on my mouse and the game crashed. http://steamcommunity.com/id/Vince2501/screenshot/542890463883493208

BTW: How do you access the new level editor?

Oh yeah, sure. Those are great too. those kind of levels are the kind that people revisit the most, the kind that are more like A-hole Mario levels are the least likely.

Just throwing this out, not trying to troll bait, and I hope the trolls have something better to do. I'm just examining what makes a good level in Meat Boy, and what makes a level needlessly hard and frustrating.

Some of the most fun levels of meat boy are (this is just for example) the Game boy levels that are short and fairly difficult on average, but can be easily completed once you understand the layout of the level. Then there's levels like Cartridge Dump warp zone which are entirely based around the difficulty of getting the bandage, if you don't care about the bandage it becomes relatively easy. Then there's levels like the Brimstone warp zone that give you different ways to complete it.

Then there comes the artificial difficulty such as in Warp Zones MMMMM or Hell Man. Where the first level or first section is relatively easy, but it all hinges on one crucial jump towards the end that's very difficult and hinges on not only trial and error but total accuracy. There is no room for error or a different manner of doing it, it has to be done exactly right.

So which levels do players generally prefer? I'm going to have to suggest levels like Brimstone, fun, challenging, and giving you varied ways of completing it. The artificial difficulty levels that I mentioned are amusing, but ask yourself how many times are you going to revisit them after completing them?

But I did collect the one on Char. To each his own I suppose.

Fighting games like Street Fighter 3: 3rd Strike. Everyone plays differently in that game, and you have to master the Parry system. In that game you're not so much playing the character and no what they can do, you're playing the player and no two people play alike... except for scrubs who pick Ryu/Ken and mash. But that applies to any fighter really.

I'd also go with the OP's listing of Ikaruga. Hardest bullet-hell game I've ever played.

El Topo and Tenebre because I get the references. ;)

Hope this isn't considered a bump. Aside from the IWBTG levels (which are absolutely insane) I've got a few of my own.

4-3X Char: God... I played this at least one hundred times. No lie. I hate this level, hate it hate it hate it hate it hate it into infinity. But I'm trying to go for 100 Bandages (up to 81 now) and I was determined to get it. What gets me is that you have to be absolutely perfect. Total accuracy. The other hard levels at least let you jump around a bit and aren't instant death. But not this one. God almighty. The Devs could've slowed down the lava by maybe 2 seconds, would that be okay? Needless to say when I finally beat it (literally played almost two hours straight) I triumphantly yelled "F U" at the screen. True story.

5-5X Nix: Not that hard unless you want that Band-aid. The first part isn't too hard if you're Meatboy, sure you have to be accurate but you're given a little bit of leeway. But if you want that Band-aid it seems like the best overall character for that is Naija. Ogmo was too slow, couldn't get up there quickly enough. Pretty much all of the other characters are just too slow. Naija comes in handy for a few Magnet-based levels. But trying to get through this level, and get the Band-aid with Naija is torture. You have to be absolutely flawless here. Once you get the Band-aid you have to position your self back where you started, and if you overshoot it you get locked out one way or another, and if you're to the left of your position and hit the switch it seems like you don't have enough momentum to make it through. Then after all that, you have to figure out how to get around those giant saw blades with her pretty random teleport. Dear god.

5-19X Magog. Not too bad, I will call out the devs in that the homing saw blade being hidden under your timer is a cheap beginner's trap. But it isn't too hard until you get to the part where you have to wall-jump with disappearing-reappearing walls lined with Saws. I tried with Meatboy and it seemed like you once you got down some sort of pattern, you'd jump with enough force to send you flying into a Saw. So I had to lame it out with Jill, which isn't fun for the first half considering her slowness. I then proceeded to float as much as possible in that wall-jump death arena, my thumb is still killing me.
