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 • 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.

Tanks! is a miniature tabletop tank battle for iPhone. Twenty hand-built missions play out on a small wooden battlefield, where shells ricochet off steel walls, mines chew through cork, and every shot you fire can come back to find you. THE CAMPAIGN Twenty missions, each a hand-designed arena of steel walls, destructible cork and open holes. Nine enemy tank types arrive in turn, starting with a slow brown tank that sits and fires, and building to fast, heavily armed opponents that hunt you through the maze, plan ricochet shots off the walls, and sidestep the shells you send at them. CONTROLS BUILT FOR THUMBS Drive with the left thumb and aim with the right. Tap to fire a single shot or hold to keep firing. Prefer something more physical? Switch to tilt aim and steer the crosshair with the phone itself. Lay mines to blow open the cork and change the shape of the fight. PLAY WITH A FRIEND Team up over Game Center. Share a four-letter room code and you both drop into the same battle. No accounts to make, no servers to find, no setup. PLAYS ANYWHERE The solo campaign runs entirely on your device, so it works with no connection at all. No ads. No in-app purchases. No tracking. Landscape orientation, iPhone only.

Verdict
The clearest difference is in-app purchases: Tanks! at none against Supernova's 10. Supernova's advantage is update cadence (every 2 days vs weekly) and device support (5 vs 1). On price, ads and iOS requirement there is nothing between them.
