Geometry Cube: Sunset Sandstorm

A one-button cube that runs across lined notebook paper: ten hand-drawn levels of spikes and loops, plus a practice mode that adds checkpoints.

📐 Geometry Cube: Sunset Sandstorm: Ten Pages of Notebook Spikes

Geometry Cube: Sunset Sandstorm is a one-button runner drawn on the lined paper of a school exercise book. A small cube moves forward by itself across the margins and the rules, timing a jump over spikes, roof thorns, gaps and loops that have been sketched into the page. There are ten chapters in all, opening at First Page and closing at Final Bell, each with a fresh backdrop and its own tune, and each a little faster than the one before.

If the name looks unfamiliar, the game also circulates as Cube in a Notebook — the app's original slug still says so. Same cube, same pages, two titles.

📄 The Rule That Kills You

The cube is either moving or dead. One misplaced jump and the attempt ends, which sounds punishing until you notice how narrow the safe windows actually are once you have heard the level's rhythm. Landing on top of a block is fine. Grabbing its side is not. That single distinction accounts for most of the deaths in the first few pages.

🎵 Tap, Hold, and the Ring

There are three ways to interact with the world and they are all the same button:

• Tap for a single jump — click, tap the screen, or press Space, Up or W.
• Hold so the cube bounces again the moment it touches down, which is what dense spike runs need.
• Yellow pads throw the cube high without any input from you, and tapping while passing through a ring adds a second jump in mid-air.

🚩 Practice Mode Is the Honest Way Through

A flag button on the menu turns on practice mode. Checkpoints are set for you as you progress, so a mistake costs you the last few obstacles rather than the entire page. It does not feel like cheating; it feels like the page finally letting you learn it. Attempt counts and best results are saved automatically either way, so progress is visible even when a chapter is refusing to break.

🎮 Controls

💡 Beating a Page You Keep Failing

• Listen before you look. Every page has a beat, and the spike spacing follows it.
• Learn the pads. A yellow pad changes the rhythm completely; the jump after it is usually the one that catches people.
• Switch practice mode on early. Checkpoints plus repetition beat a lucky run.
• Do not jump at the spike. Jump so that you land where the spike is not — the input always comes earlier than instinct suggests.
• Clear the page completely. The next chapter only opens once a page reads 100%, and the last few percent is usually one cluster of thorns you have already survived once.
