Mercury arcade
Astral Crown: a browser kingdom building game
Build by daylight and hold the night. Astral Crown combines a pixel-art settlement, a travelling ruler, and a survival campaign you can return to from your Mercury account.
Play Astral Crown in your browser
Build your colony and protect the crown
Begin in practice to learn the world, or sign in and start a saved campaign. Move your ruler through the settlement and use the on-screen prompts to spend coins, recruit settlers, and develop your defenses. The scene alternates between daylight preparation and nighttime danger.
Watch the context bar for nearby offers and their coin costs. Your colony, settlers, and crown matter across the campaign. Keep an eye on the rifts and the changing state of the world rather than treating every session as a new arcade flight.
Return to a saved kingdom
A signed-in campaign keeps the colony in your account. Use the pause and Save & exit controls before leaving, then return through Continue saved colony. Wait for save confirmation so you know which progress is preserved.
Practice does not save a colony to your account. Starting a new saved world can replace an existing colony after the game asks you to confirm; earned arcade points remain. If you already have a settlement you want to keep, continue it instead of confirming a replacement.
Choose campaign play or a shorter challenge
Astral Crown suits a player who wants to revisit a place and develop it over time. Endless Invaders offers a shorter shooter run, while Planet Resonance tests a growing memory sequence. All three fit within the same arcade, with separate game totals and an overall account score.
Browser game questions
Can I save my Astral Crown kingdom?
Yes, when you sign in and play a saved campaign. Use the game's save controls and wait for confirmation, then return through Continue saved colony. Practice is separate and does not save to your account. Starting a new world asks for confirmation before replacing an existing saved colony.
Is Astral Crown multiplayer?
The current game is a colony survival campaign controlled by one player. The arcade has shared leaderboards and an overall score system, which let players compare accepted points. That does not mean players build the same kingdom together. Use practice to learn the controls before starting a saved campaign.
