Kellerbier

This is an early alpha. Four floors of a planned seven are fully playable start to finish, with a full run taking roughly 30–40 minutes. Content updates arrive regularly as the remaining floors are built.

Alois is at his grandparents' for Sunday lunch, the way he is every Sunday, and he has gone down to the cellar for another bottle of the good Pfeitinger. The crate is empty. The full one next to it is Pfeitinger too, and the label is wrong: brewed according to the new Bavarian purity law. Water, malt, hops — and raisins.

So Alois takes Opa's drinking backpack off its hook, fills it with what is left of the tainted crate, switches it from trinken to schießen, and heads south to find out who is responsible.

Kellerbier is a fast-paced roguelike bullet hell in the tradition of The Binding of Isaac and Enter the Gungeon: procedurally generated layouts every run, rooms full of hostile vermin and folklore horrors, dozens of items that combine in unhinged ways, and multi-phase bosses at the bottom of each floor.

What makes it unique is Promille: Drink and your shots hit much harder — but the room sways, blurs, and closes in. How far you dare push your intoxication is the core risk/reward choice of every run.

THIS IS A PLAYTEST — TELL ME WHAT BROKE

The first time you boot, the game asks if you'd like to participate in the anonymous playtest telemetry (tracks win/loss rates, floor times, and item synergies). It is completely anonymous, sends no personal info, and can be toggled off anytime in Settings.
