Claim open space away from hazard clusters; don’t start pinned near spiked rocks.
Biggest mistakes
- •Ending turns aligned with hazards: Flush converts position into collision damage wipes.
- •Overextending: teleport movement punishes chasing and exposes your backline to wave angles.
- •Ignoring sustain swings: Rest heals a lot and extends the hazard game.
How you actually win
- •You never allow a Flush line to push multiple cats into objects.
- •You keep a ‘safe lane’ (open space behind your units) before the wave hits.
- •You pressure hard enough that Rest can’t reset the fight repeatedly.

Win conditions
- •You never allow a Flush line to push multiple cats into objects.
- •You keep a ‘safe lane’ (open space behind your units) before the wave hits.
- •You pressure hard enough that Rest can’t reset the fight repeatedly.
Positioning rules
- •Treat every object behind you as lethal during Flush turns—stand with open tiles behind.
- •Spread laterally so one wave can’t line-push the whole team into the same hazard cluster.
- •Keep one responder to rescue a unit that gets pushed into danger.
- •Don’t chase teleport blindly; stabilize the center and force him to come to you.
Tempo plan
Opener (rounds 1–2)
- •Claim open space away from hazard clusters; don’t start pinned near spiked rocks.
Midfight (stabilize)
- •After each wave, re-center and re-spread; assume another Flush is coming.
Finisher (close safely)
- •Commit burst when he cannot safely Rest; avoid late-game hazard attrition.
