Player Tips

  • Take breaks when frustration builds. Coming back after a few minutes often makes the solution or the right timing click naturally.
  • Audio cues exist for a reason. Play with sound on at least once to learn what the game communicates through audio versus visuals.
  • Try playing left-handed if the game allows it (or vice versa). It sounds odd, but changing your input hand can reveal patterns your dominant hand was autopiloting through.
  • Try the opposite of what keeps failing. If you are playing aggressively and dying, play defensively. If you are playing cautiously and timing out, push forward. The answer is often the reverse of your instinct.
  • If there are multiple modes or difficulty levels, start on default. It is tuned for first-time players and gives you the experience the developer intended.

Controls and Rules
