Cube Jump is a complete, sellable one-button 3D casual game. Hold to charge and release to jump from big cube to big cube: the longer you hold, the further you go, and the cube flips in the air. Land near the centre for PERFECT combos (2, 4, 6, 8 and 10 points), tip off an edge or miss and the cube shatters.

The endless course generator is seeded and deterministic, gets harder with smaller platforms and bigger gaps, and adds moving and crumbling platforms and gems. Six visual themes (Peach Dream, Mint Lagoon, Lavender Dusk, Sunset Fizz, Midnight Neon, Ocean Breeze) crossfade every 25 platforms. Collect gems to buy 12 cube skins in a rotating 3D shop or to revive once per run (with a hook for a rewarded ad on mobile).

The Daily Run gives everyone the same course from the UTC date, with its own best score and leaderboard, and assisted runs are kept off the main board. One switch toggles Classic (plain cubes, chiptune) and Modern (moving and crumbling platforms, gems, revive, input buffer, charge meter, edge assist, camera shake, relaxed music, anti-aliasing and glow); about 40 player settings can be locked by the developer in one config resource. The title screen has a bot playing behind the menu.

Includes a full Options menu (video, audio, rebindable keyboard and controller, gameplay assists, accessibility, colour-blind filter), touch, keyboard and gamepad support, landscape and portrait layouts, 16 achievements, stats and 2 leaderboards with optional GodotSteam hooks (App ID 480 test), cloud-safe saves, a rules check with 23 checks and a 209-check smoke test, 20 real screenshots, marketing slides and a 55 second autoplay preview video. All third-party art and audio is CC0 (Kenney, Juhani Junkala, Pixel-boy) with every file's source documented; the rest is code-generated art and synthesized audio.
