Sunborn is a cosmic incremental where you accumulate mass into an expanding sun, triggering exponential growth through layered upgrades that compound toward increasingly massive scales. The progression moves from linear gains through exponential jumps, building toward genuinely game-altering transformations. Best suited for players who enjoy watching numbers escalate dramatically and appreciate deep upgrade synergies.
About this game
A cosmic idler that goes SUPERNOVA. Drag mass into your sun, grow it from spark to stellar and watch every upgrade stack. Linear. Exponential. Then genuinely SUPERMASSIVE.

Thanks for all the feedback! This update makes the start clearer and the collector much more satisfying. ★ NEW & IMPROVED- Faster collector: orbs follow you 2–3x faster and stay caught when you move quickly- The Nexus pauses the game (including the demo clock), so take your time picking upgrades- Orbs that fly off-screen come back from the other side instead of being lost- Buying many upgrades in a row raises prices for a bit; they cool down as you play, and the Nexus shows by how much- How to Play opens the first time you play (only once), with clearer cards- New tips at the right moments (gold rings, fast hits, the Red Dwarf cap, cyan Quantum Cepheids), shown one at a time- Slow starts get a gentle "solar tailwind" to help your star ignite ★ FIXES- Chinese: pink block after the orb count on multi-orb catches is gone- German: umlauts and ß now use the game's font- No more lag-spike/stutter when collecting your first orbs- Controller: cursor speed fixed on 4K screens; pressing A in menus no longer toggles the collector- Early-game +30% bonus now also applies to dragged orbs- Quantum Cepheid's 5x field always opens, even if another field is active- The collector hides while paused- Easier-to-read fuel display- End screen briefly ignores input, so no accidental NEW RUN occurs- Leaderboard names in more languages (Polish, Turkish, Korean and more) display correctly ★ FEEDBACK- Ratings no longer come pre-selected; 1–3 star ratings ask for a short comment so we can fix what bothered you Scores may climb higher than before, the collector is just that much faster now. Have fun!
