Splitline

About the game

A glowing precision platformer of ten-second courses and instant retries. Guide Signal, a small diamond of light, along thin lines through the dark. Race the ghost of your best run through 60 courses in six worlds, climbing from gentle first lines to courses that are almost impossible. In development for iOS and Android.

Features

Ten-second courses and instant retries. One more run is always one tap away, with no lives, energy or waiting. After a fall you are straight back at the start, and the clock waits until you move.
Move, jump, wall-kick and dash through 60 courses in six themed worlds. Each world brings a new idea, from six gentle teaching courses to final courses that are almost impossible, and the Cold Start sprint runs the first three back to back.
Race the ghost of your own best run, recorded on your device, and see the time you win or lose.
Find the faster line: some courses hide an optional route you only discover by crossing it.
Finish a world to earn a new trail colour for Signal, six in all, and pick yours in Settings.
Lines of light: a glowing course, a trail behind Signal, sparks where it meets the line and bursts of energy at every finish. Every world has its own backdrop of distant light behind the course and on its world card. Reduced motion and a glow setting calm it down.
Each world has its own music loop, with sound effects in step with every landing, dash and finish.
Mirrored and resizable touch controls, larger text, practice speed, an auto-hold jump, haptics, and English or Swedish. Plays fully offline.

Story

Every course has a recorded line. Signal finds a second trace through a gap the map says is closed, and follows it. Your rival is your own best time.

Manuscript

Every course has a line.

A thin cyan path cuts through the dark. There is a start, a finish, and a route someone has already drawn.

Every line has a time.

A pale ghost follows the recorded path. You can chase its rhythm, learn its turns, and try again.

Then you find the gap.

A faint trace slips away from the expected route. Signal catches the light and takes a closer look.

Run it your way.

Find the opening. Make the jump. Leave a better time behind.

Art direction

Lines of light on near-black: a glowing orange Signal, thin cyan course strokes and small magenta hazards, with soft bloom and light trails. The glow never hides an edge, and every shape reads without colour.
