Tips and tricks

  • Look one step ahead of your character. Reacting to what is under you is too late; reacting to what is coming is exactly on time.
  • Take a short break after three or four failed runs. Arcade games punish tired eyes more than any other genre.
  • Find the rhythm. Most arcade games have an underlying beat — taps, jumps or moves that fall on a regular interval — and once you feel it, your accuracy jumps.
  • Learn the first thirty seconds perfectly. The opening is the same every time, so it should never be where you lose.
  • Because this is a Idle game, check back regularly and spend everything — idle games reward frequent short visits.
  • Because this is a Hypercasual game, find the rhythm of the single mechanic — that is the entire skill.
