Supernova: Idle Star Forge
Fuse hydrogen into stars, watch them evolve visually, then detonate for permanent upgrades.
Fuse hydrogen into a living star. Grow it. Then blow it up — on purpose.
SUPERNOVA is a premium-feel idle game about running a cosmic forge. Tap to spark fusion, build 12 generators from Hydrogen Wisp to Singularity Seed, and watch your star physically evolve — protostar, blue giant, red supergiant — until it is ready to collapse. Detonating it is the point: every supernova grants Neutron Cores, permanent power that makes each new universe faster than the last.
WHY YOU'LL STAY
• Real progress while you're away — production continues offline (extend the cap up to 24 hours with research), and a welcome-back doubler greets your return
Read the full description
• A star that actually changes — five visual stages, rendered live, no canned art
• Prestige that feels like a finale — a hand-built supernova cinematic, then a stronger start
• Numbers that get gloriously big — Million, Septillion, and far beyond
• Milestones every few minutes early on, deep multiplier stacking later
• Daily missions and streaks that respect your time
• 20 research upgrades that shape every run
FAIR BY DESIGN
• No ads. None.
• No energy bars, no forced waits, no progress walls
• Fully offline — no account, no sign-in, no internet required
• Nothing collected, nothing tracked
• Optional purchases exist (time warps, photons, a one-time Supporter Pack), and the entire game is balanced to be completed without spending anything
THE LOOP
1. Tap your star and let generators forge Stardust
2. Hit ownership milestones — each one doubles a generator's output
3. Buy research, stack a Photon Surge boost, fill your Piggy Bank
4. Reach collapse readiness... and go SUPERNOVA
5. Keep your Neutron Cores forever. Start again, faster.
Built by a solo developer in SwiftUI and SpriteKit. Every pixel is procedural — no asset packs, no stock art. Dark theme, tuned haptics, Reduce Motion respected.
Your first universe is waiting. It starts with one atom.
Ratings
The game is great but after a while you reset so much times that there’s not a lot to do after a point.
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
Been enjoying it all day so far but boy does it make my phone hot.
