Jumpurr

The tower has no top. Pet every cat you pass — the ones you skip take it personally and come after you. Three hearts is all you get.

The tower has no top.

Jumpurr is a cosy endless climber. Hop from platform to platform, pet every cat you pass, and see how far up you can get before gravity has an opinion about it. Do pet them, though: a cat you climb straight past takes it personally.

The higher you climb, the stranger the weather gets. The blue sky darkens through dusk into deep space, platforms turn from grass to stone to riveted metal, the stars come out — and above the atmosphere the cats put their helmets on. So does your kid.

HOW IT WORKS • Two buttons to move, one to jump — or arrow keys if you have a keyboard • Platforms are one-way: hop up through them, land on top on the way down • Walk into a cat to pet it, and it stays happy for the rest of the run • Get close to one and climb past without petting it, and it puffs up, leaves its platform and comes after you — one or two at a time. A scratch costs a heart, then it heads home for good. Pet it while it is still puffing up and all is forgiven • Three hearts. A long drop costs one, a very long drop ends the climb • Your score is the highest point you reached in metres, and your best is kept on this device — no leaderboards, no sign-in

NO NONSENSE • No ads • No accounts, no sign-in, no tracking, no analytics • Nothing to unlock, no energy timers, no waiting • One optional tip jar — three one-off in-app purchases that unlock nothing, give no advantage and are not restorable. The whole game is here without them

Choose a boy or a girl, pick a line through the tower, and go and be nice to some cats.
