How to unlock the Bathroom breaks are for the weak achievement in Dustforce - Definitive Guide
To unlock the red levels, you have to obtain all available red keys. In order to do this, you have to score SS on every single gold level in each hub world. To unlock all gold levels, you have to SS all silver levels, and to unlock all those you have to SS all plain ("bronze") levels. When you have enough keys, you have to climb the chimney in the central hub area. Here's how (courtesy of youtube user Kuroonehalf):
If you have any questions or something to add, feel free to leave a comment and I'll get back to you.
Once you have all 16 red keys climb to the top of the tower. After unlocking and entering ! hub, go to the Exa Difficult level. Simply jump to the right and destroy the 3 big crystals and the achievement will unlock.
Glitched on both versions. Red levels are the ones you will find in the ! hub (which you can enter after getting all 16 Red keys after SS-ranking every other level in the game except for the Tutorial; check the video under Master of the Custodial Arts to understand how to reach this hub) and this trophy requires to clear one of them without dying. Go to “Exa Difficult” level, choose Dustworth, dash-jump to the right and dash-jump again while mid-air to land on a platform with 3 big dustblocks floating above it. Destroy them with Heavy attacks and you will clear the level and get the trophy (thanks to A1rPun for explaining the method). Do note, however, that the trophy is positively glitched on both versions and may randomly pop when you are doing other things (if I recall correctly, I got it after clearing Yotta Difficult for my 1st time on version 1.00, whereas a friend of mine got it while watching a leaderboard replay on version 1.01).
