Cube in a Notebook

A little cube lives in a school notebook and dashes across its lined pages. Spikes, ceiling thorns, jump pads and jump rings are doodled in pen right in the margins.

There are 10 pages to beat, from "First Page" to "Final Bell". Each one brings a new idea and its own music, while speed and difficulty grow step by step.

One touch means one mistake, and the attempt starts over. Your attempt count and best progress are saved, so you can see your skill grow.

Practice mode places checkpoints automatically as you go: drill a tricky section, then clear the whole page in one run.

Progress is saved automatically. The game runs on computers, phones and tablets, in any screen orientation.
