Too easy → boredom. Too hard → freeze. Crystal rush lives just above your skill comfort zone.
| Domain | What It Looks Like | |--------|--------------------| | | A no-HUD FPS run where you trust audio cues and peripheral vision. | | Design | Sketching directly in vector without layers or history — committing to every stroke. | | Writing | Drafting in a plain text editor with spellcheck off, deleting nothing until the rush ends. | | Coding | Live coding in front of an audience without undo — debugging forward. | | Music | One-take recording with no punch-ins, embracing finger slips as rhythm. | usepov crystal rush
