Deep Space Idle

Deep Space is a simple cliker game that aims to be easy and comfortable to play. Grow your platoon by stacking cash and buying new ships, so you can stack more cash and buy even better ships! The game has only one mode, you can just start playing right away. Clickers items multiply your output damage, which in turn will earn you more cash. Ships are generators and as soon as you buy them, you start earning. You can exchange your current stack (currency, ships, clickers) for a global multiplier (prestige) that will reset the game but will help you upgrade faster.
