About the game

Sisyphus Paradox mixes traditional side-scrolling shoot 'em up gameplay with many roguelike mechanics, such as procedurally generated star maps to explore, bonuses that are persistent between runs, and multiple different builds you can try to conquer your enemies. Course through hand-drawn battlefields, lose, try again, until you solve the Sisyphus Paradox.An ordinary person finds themselves flung across the galaxy. They are lost far away from home, with a voice in their head as their only guide and companion. Strange alien looking creatures are in pursuit. Help them fight their way back to Earth. Features 2 Playable Ships: Each has very distinctive mechanics that go well beyond simply having different stats. 56 Unique Items: You have weapons, passives and active-use specials, all of which can be upgraded, and some can change significantly as they level. 10 Timestreams: Each more challenging than the last. As you become better at the game, more options are revealed to you. The Antagonists: There are three different factions to face, each with their strengths and weaknesses, as well as their own Bosses and Minibosses. Infinite Universes: Choose your path across the stars as each run will offer you a new map to explore, full of random encounters and enemies to deal with. Multitude of Options: Each ship has slots for two weapons, two passives, and two specials, giving you a multitude of build options with which to approach each game. Sisyphean Task: Every time you are defeated you set out on a new journey, hopefully moving closer to your end goal, this time with new bonuses to help you out.
