Dashmetry / Challenge Rush

Dashmetry is a fast-paced rhythm platformer, also known as Challenge Rush, where you guide a shape-shifting icon through neon obstacle courses filled with spikes, portals, slopes, gaps, and sudden movement changes. Time every jump, gravity switch, flight path, and dash carefully to survive each level and reach the finish.

• Fast rhythm-based platforming gameplay
• Auto-moving icon with simple one-button controls
• Spikes, gears, slopes, portals, gaps, and narrow passages

• Built-in level editor for creating custom maps
• Community-created levels and shared challenges

• Normal Mode – Complete designed levels from start to finish without crashing and aim for better scores.
• Practice Mode – Use checkpoints to repeat difficult sections and learn the timing before attempting a full run.
• Endless Mode – Survive randomly generated obstacle courses that become harder the longer you continue.
• Level Editor – Build, test, and share your own rhythm-based levels using obstacles, portals, triggers, decorations, and music timing.

Dashmetry changes how you play by transforming your icon during levels. Each form uses simple controls, but movement and timing work differently.

• Cube – Jump over spikes, gaps, blocks, and platforms.
• Ship – Hold to fly upward and release to descend.
• Ball – Switch gravity between the floor and ceiling.
• UFO – Tap to bounce upward while moving through the air.
• Wave – Hold and release to move diagonally through tight spaces.
• Robot – Hold longer to perform higher jumps.
• Spider – Instantly switch between the floor and ceiling.

Portals can also change your gravity, speed, size, or movement form, forcing you to react quickly as each level changes.

Dashmetry rewards practice, memorization, and precise timing. Use Practice Mode to learn difficult sections, then return to Normal Mode to complete the entire level in one run.

Progression includes:

• Level completion
• Practice checkpoints
• Endless Mode scores
• Leaderboard rankings
• Achievements
• Custom level creation
• Community level sharing
• Icon and skin customization

The more levels you play, the better you become at recognizing patterns, reacting to portals, and staying synchronized with each level's rhythm.

#### PC

• Left Mouse Button — Jump, fly, or perform the current movement action
• Spacebar — Jump, fly, or perform the current movement action
• Up Arrow — Jump, fly, or perform the current movement action

The same input behaves differently depending on your current form. For example, the Cube jumps with each press, while the Ship rises while the input is held and descends when released.

Dashmetry, also known as Challenge Rush, is a browser-based rhythm platformer built around timing, focus, and repetition. Guide your icon through dangerous neon levels, avoid obstacles, master seven different movement forms, and use Practice Mode to improve difficult sections. With quick restarts, music-driven gameplay, community levels, Endless Mode, and a built-in level editor, Dashmetry offers a challenging arcade platforming experience directly in your browser.
