Most runners never end. This one does. Twenty worlds, nineteen Wardens, and a long way home — then an endless mode that never lets you finish.
You are JETT, the last skyrunner. Stranded across a distant galaxy of twenty hostile worlds, you're armed with a jetpack that runs dangerously hot and a voice on the radio pointing you toward home.
Hold thrust to climb. Hold it too long and the pack redlines, cuts out, and drops you. That single decision — when to burn and when to back off — is the heart of the game. Kills cool you down, so flying aggressively is also flying safely.
This is a runner with an ending: 80 levels across 4 acts, all of it the work of one person, each world introducing new hazards before culminating in a Warden battle. Reach the Aether Heart, face what's waiting there, and fly home.
Every world changes the rules.
Each world teaches a new skill, then expects you to master it against its Warden.






Every world is guarded, and every fight is built around the skill its world spent four levels teaching you. If a Warden feels impossible, you're usually missing the lesson rather than the reflexes.
Beat a Warden and its world relights on the route map. Twenty lamps, one for each world you took back.
The campaign has an ending. This doesn't. Assault is open from the main menu from the moment you install — you don't have to finish anything to earn it — and it's where the game stops teaching and starts asking.
The run moves through sectors that change biome and enemy roster as you go, and the speed climbs the whole way. Nothing resets. The only way out is down.
Between sectors the run pauses and offers you two upgrades. You take one, and it stays with you for the rest of the run. Stack the right ones and a run compounds; take the obvious one every time and it plateaus.
One named seed a day, the same run for everyone who plays it, reset at midnight. No second attempt at today's — if you throw it away at 800m, that's today's answer.
Milestones you pass on the way up, a local high-score table for your best runs, and a death report at the end that tells you exactly what killed you and how far you got.
Every run ends with a shareable run card — your pilot, your distance, your title for the run — rendered as an image you can send to whoever you're trying to beat.
Bank up to three charges and spend them when the moment is right. Chain kills and close calls to keep the burn going. Charges carry between levels, so the decision is never just "now or never" — it's "now, or at the Warden".
The last band of the heat gauge is where the pack is about to cut out — and where it gives you the most. Flying deliberately inside it is the difference between finishing a level and owning it.
Every level has goals beyond surviving it. Eighty levels, and clearing one is only the first of the three things it wants from you.
Hold a side of the screen to fly. Drag to move. Auto-fire is on by default, so the whole game is playable one-handed on a train.

It's free, and it's paid for by adverts. Here's exactly where they are, so nothing is a surprise: an optional "watch something for one more go" offer when you run out of lives, and an occasional full-screen advert between levels — never during a run, never before you've played for a while, and never on a Warden.
Nothing is locked behind money. Every weapon and every upgrade in the game can be earned by flying, and the shards that buy pilots and thruster colours are earned the same way. What you can pay for is a shortcut to something you'd otherwise fly for, or the adverts gone — never a weapon nobody else can reach. If someone beats your run, it's because they flew it better.
No accounts, no logins, no cloud saves. Progress is stored on your device and nowhere else, which also means deleting the app deletes your save — permanently, and I can't get it back for you.
