Qrth-Phyl

In qrth-phyl, you manoeuvre through three-dimensional stages, leaving a persistent tail behind you that you must avoid. The stages are algorithmically generated and adapt to how you play. The game also includes documentary material about the development and origins of Blockade, snake and worm video games from 1976 to today.

Game modes

• Sequence: play through an infinite sequence of algorithmically generated stages. Collect dots to unlock each exit and generate the next stage, which is informed by how you played.
• Seed: create a single infinite stage from a chosen seed, which is recorded on the leaderboard. Optimise your score by finding the best seed.
• Box: play in a fixed-size 3D stage and chase a high score.

Scores and soundtrack
