One Button Dungeon

One Button Dungeon is a minimalist dungeon crawler built entirely around a single input.

Press A to take one step forward.
That’s it.

Every step triggers a random event:

• A fight you didn’t prepare for

• A trap you absolutely should’ve seen coming

• Treasure (finally!)

• A moment of rest

• Or… something very strange

There are no sprites, no animations, and no mercy — just clean black-and-white UI, procedural events, and an endless descent measured by how long you survive.

Features

• One-button gameplay (perfect for quick sessions)

• Procedural dungeon events

• Permanent relic choices at key depth milestones

• Rare secret events that permanently change your run

• Multiple ending titles based on how badly you fail

• Persistent best scores

• Tiny synthesized sound effects (no audio files)

• Designed specifically for Playdate

There is no final boss.
There is no victory screen.
Only a number that goes up… until it doesn’t.

How deep can you go before the dungeon decides it’s done with you?
