Each game has different mechanics: +- vim-maze: Efficiency makes sense (optimal path vs actual) +- vim-sudoku: Efficiency concept unclear (what's "optimal" editing?) +- vim-snake: No efficiency concept at all + +Better to let each game define scoring that fits its mechanics. + +### Tasks Completed + +#### 1. Removed Efficiency Metrics +**Removed from ScoreManager:** +- `editKeystrokes` - No longer tracking +- `optimalKeystrokes` - No longer calculating +- `efficiency` - Removed entirely +- `EDIT_KEYS` filtering - Removed + +**Now tracking only:** +- `timeValue` - Elapsed time in milliseconds +- `totalKeystrokes` - All keys pressed +- `finalScore` - Calculated score (0-1000) + +#### 2.
