What's New in Supernova

1.3.15

September 15, 2026

The Long Work — a career, in order, with a voice Supernova could always tell you what there was. It could never tell you what you were doing: past the tutorial the honest answer was "more of this, and eventually a row lights up". There is now a 48-chapter campaign. Chapter twelve does not exist until chapter eleven is sealed, so there is exactly one next thing at every depth and it has a name. Nothing ever repeats — every chapter is written once and retired when you seal it. The asks rotate on purpose across eighteen different things a career can do, so it never becomes a depth ladder with prose on it. Six acts, each set on a world your own detonations put on the Atlas. When the written chapters run out, the Atlas keeps setting new ones. Sealing a chapter is a tap, never automatic, because the page is the reward and we would rather not scroll it past you while you are looking at the Forge. The Case — the first thing here you cannot see coming A supernova now sometimes turns something over in the crust. Sixty relics across twenty charted worlds, each with a line about whoever left it there and a hole in the shelf until you find it. Roughly eighteen detonations in a hundred turn one up; twelve without a find makes the next one certain. The odds are printed on the screen. Relics cannot be bought, hurried or re-rolled — not for money, not for photons. Detonating is the only way, which is the thing you were doing anyway. Neither of these grants production The bar you detonate against is paced on your own output, so any permanent multiplier buys one faster run and is absorbed forever after. Both systems pay photons and text, and that is deliberate. In your language All of it — every chapter, every epilogue, all sixty relics — is translated into every language Supernova ships in. None of it is English-only. Forge on.

I had fun

I lost all my progress.

Response from developer

NexusZiren — a 5-star review after losing all your progress? You've got the heart of a true star-forger (or a saint). Genuinely sorry the save vanished on you — if it ever happens again, hit us at contact@oshi-messenger.com and we'll do our best to help. Thanks for the incredible sportsmanship. 🌌

Fun but too short

Was a fun game until I reached the top of the leaderboard in less than 4 hours, would continue playing if there was more to do

Response from developer

GrayImp20 — top of the leaderboard in under 4 hours? Respect, but also: we clearly need to build a taller mountain. More endgame to climb is exactly what we're forging, so hopefully there's soon a good reason to defend that #1 spot. Thanks for the fun run!

Pretty fun game

Been enjoying it all day so far but boy does it make my phone hot.

Response from developer

JTGibbs — forging stars is apparently hot work, who knew. Kidding aside, a toasty phone means we've got performance to tune, and cooling things down is on our list. Thanks for playing all day despite the heat — send a note to contact@oshi-messenger.com if it gets rough and we'll dig in.
