A real roguelite you can play with one thumb
Short runs, big bosses and a reason to go again, made to play properly on the bus.
One thumb, real depth
16 upgrades with gold Ascended tiers, 14 Evolutions that redefine your build, and fire, frost, poison and lightning that combine into reactions.
10 chapters, 20 boss fights
Every wave ends in a boss with its own trick. Then try the Daily Rift, a new challenge every day, or Endless, where the waves never stop.
Fair to play for free
Ads only appear between runs and rewarded ads are always optional. One Full Game purchase removes the ads between runs.
Slide, ricochet, upgrade, repeat




Easy to pick up, hard to put down
Slide your paddle

Build your run
Level up and pick from three upgrades. Stack them into Evolutions, reroll a bad hand, and take down the boss.
Come back stronger
Every run earns shards, win or lose. Spend them in the Workshop on 12 permanent perks.
