Tiny Knight and the Corrupted Crystal

Tiny Knight and the Corrupted Crystal is a single-player action roguelite built around an incremental power curve. The knight's corrupted sword drains his own health for as long as he stays in a level, so the health bar doubles as the level timer and there is no separate countdown; upgrading maximum health buys survivability and time in the same purchase. Attacks fire automatically as a 360-degree pulse, leaving positioning as the only moment-to-moment decision, and every kill shortens the player's ability cooldowns. Death is the progression system rather than the fail state: banked gold and the permanent skill tree both survive it, so each run funds the next. Five biomes end in boss fights, and an elemental infusion system lets the player commit to fire, frost or lightning — or to the corruption itself, which is stronger and changes the ending.
