Unlocked a crap-ton more in Super Meat Boy until my wrist started hurting: Got 6 levels left to beat before I can play the absolute final boss, and 100% the first 3 chapters light and dark in the process. I also managed to climb to 2nd place (from 3rd, easily a good 2000 ranks) in my Steam Friends list scoreboard ((Current rank: 6647, Time: 2923.64, Levels Beat: 236. Have fun catching up.) Sorry Myroc, I'm ahead of you now. Naxza, you're next in my crosshairs). Also found and beat another glitch level, and unlocked about 3 more characters with another on it's way after 3 more bandages (easier said than done). No news yet in regards to The Kid (IWTBTG); his levels are still unmerciful to take on despite my skills, and I recently took on Ogmo's stages. Sheesh.
I realized, the more gamebreaking the character you're to unlock, the harder they are to obtain. I have a feeling Mr. Minecraft (as labeled) might be able to create blocks as well as destroy them after being unlocked. Understandable, seeing as 100 bandages would be the limit, and he'd no longer be needed to make it a cakewalk to get them, as well as beat just about any level easily.
EDIT:
Case in point: I just beat a level by exploiting Flywrench's no-bounce wall climb, and managed to beat the par time of a level by 18 seconds flat (par:30, Me:~12 (replay -/+ .10)) by wedging him between a narrow ledge and a saw blade (4-1 for those curious enough to try it out). That's how you climb ranks fast. Oh yeah, and make that 5 levels now before I reach the true end.
EDIT EDIT:
Make that 1 level now.
My hands are hurting now. Rank 6167 now.
EDIT EDIT EDIT:
WOO! No levels left. I can finally take on the true ending. This is going to be brutal. Just like the last level in the light world, except many many more sawblades than necessary, and a far more narrow time gap to make my moves. I'm also now 20 ranks below Naxza. All I need to do to beat him is get better times/more A+'s (overall, shave 70 seconds total off), or beat one more level. ^_^
