Organic Evolution

Organic Evolution is a neon-themed platformer set in an underwater microcosm. You guide a tiny, one-eyed organism through procedurally generated levels, finding keys and reaching the exit.

Navigate each level

You can jump several times while airborne, with the available jumps shown on the top panel. Your jump reserve is 5 in Classic and Extreme modes and 10 in Explorer mode; it is restored when you land. You can break some blocks above or below you, and the blocks regenerate after a while. Coins may be hidden behind them.

Each level has a key, shown as a glowing golden flower, that unlocks the exit vortex. In Explorer mode, you must find 5 keys per level instead of one. The three modes are:

• Classic: play through 8 levels of increasing difficulty, with 5 mid-air jumps.
• Explorer: play extended levels with double the map height, 10 mid-air jumps and 5 keys to find on each level.
• Extreme: play through the same levels as Classic, but see only within a circle of light around your character. The rest of the level is dark, while keys and the exit glow faintly.

Enemies and hazards

Jellyfish float through the air along sinusoidal paths. Runners patrol platforms and fall to their deaths if you break a block beneath them. Snails, which have shells and spikes, also patrol platforms and can be killed by falling. Starfish rotate as they fly along paths, Pulsars appear and disappear and pose a danger during their active phase, and Toxic Algae remain stationary on the floor. Defeating enemies drops gem crystals that you can collect for points. When an enemy kills you, both you and the enemy are destroyed, and you respawn on the spot.

Points and survival

You earn shield spores automatically for every 2,000 points, up to a maximum of 10. Each spore absorbs one enemy hit, then disappears and grants brief invulnerability. For every 25,000 points, you regain one life, up to a maximum of 10. The HUD displays your health, current level, remaining mid-air jumps, shield spores, key status or Explorer key count, and score. Your health is shown as hearts, to a maximum of 10; a bar beneath the score tracks progress toward the next level.

Visuals and features

Levels use a neon style against a dark background with a hexagonal grid, and each level has one of 8 color themes. The game also includes progress saving, achievements and leaderboards through Steam, and an atmospheric soundtrack.
