Krypta

Beneath the old abbey lies a crypt, and at its bottom sits the Eternal King. He refused to die. Since he put on the crown of bone, the dead of the whole valley have known no rest.
Eight floors down. No one has ever come back.

Krypta (The Crypt) is a fast, room-by-room roguelike shooter in the spirit of The Binding of Isaac. Pick a hero, fight your way down through eight floors, stack up items that change how you play, and end the King's reign — or die and try again with a new crypt.

What's inside

• Three heroes who play differently: the tough Knight and his tumbling hammer, the quick Rogue with a storm of knives, the frail Mage whose spells fly straight through enemies.
• Eight floors, five places — the Crypt, the Catacombs, the Sunken Cells, the Abyss and the Throne Room — each with its own look, music, hazards and favourite monsters.
• Nine bosses. Every place has two; the seed decides which one is waiting. All of them telegraph their attacks and get meaner below half health. At the very bottom: the Eternal King.
• 32 items whose effects stack: exploding shots, poison, an orbiting orb, armour, a second life, a lantern that reveals the map, and more. Treasure rooms offer a choice of two; altars trade an item for a heart.
• Ten kinds of enemies, ambush rooms, pits and spike traps.
• Seeded runs — type in a seed and get exactly the same crypt, to race a friend or to practise.
• A collection that remembers every item you have ever found.
• Original chiptune soundtrack, a different piece for every place.
• Plays in English and Polish.

The game is in active development — bug reports and ideas in the comments are very welcome. The version number is in the corner of the title screen; please mention it when reporting a bug.

Made by one person with a lot of help from AI (Claude): the code, pixel art and music were written with it.
