Tips and tricks
- Do not tilt. After a bad round, the next one is a fresh start; the player who resets emotionally usually wins the set.
- Short, frequent matches build skill faster than marathon sessions.
- In shared-keyboard games, agree on who uses which keys before you start — hand collisions cause more losses than skill does.
- Cooperative modes reward splitting roles: one player handles offence while the other covers, rather than both rushing.
- Because this is a Escape game, click everything once, then think — escape games reward a full inventory of clues.
