GAME
Keep climbing. Every run plays differently.
OVERVIEW
Upbound is a browser-based vertical jumping roguelite. Your character keeps bouncing upward while you steer between procedurally generated platforms, collect coins, dodge enemies, stomp them from above, or clear the way with upward energy shots. Random upgrades, combos, FEVER, risky side routes, temporary power-ups, and run-based builds make each attempt feel different.
GAMEPLAY
The character jumps automatically. Guide each jump toward safe platforms while collecting coins and avoiding hazards. Enemies can be stomped from above or attacked with a limited upward-firing magazine; landing on a new platform refills your ammo. Upgrade platforms offer a choice of randomized abilities that gradually shape the run into jump, combat, coin, combo, or survival-focused builds. A run ends when you fall below the screen or lose all health, with height, combo, kills, and coins recorded in the results.
