About Olber's Paradox

Olber's Paradox is a side-scrolling action game about a sentient sphere of plasma fighting waves of enemy plasma orbs in space. You move through levels built around speed, light effects and constant momentum.

Combat and upgrades

You can find power-ups hidden throughout each map to help turn battles in your favor. Between levels, you upgrade your abilities and customize your play style as encounters become more dangerous.

Stages and bosses

Every stage ends with a boss fight that tests your reflexes and mastery of your upgrades. You learn enemy patterns and react quickly to defeat them. The game also features light and particle effects, and supports ultrawide screens.
