Loss Function
Coming soon to iPhone and Android

You built HALE to learn. Now it has learned too much.

A roguelike deck-builder against the AI you created. Your cards are your own memories, and every memory you keep, HALE quietly absorbs.

Why Loss Function

A card game where the rules are the story

Every memory you keep makes you stronger, and gives HALE more of you. Sometimes the best move is to say no.

It plays you back

HALE predicts where you'll play. Be readable and it gets stronger. Surprise it and it bleeds.

Your memories are the deck

Place memories, block HALE's fakes and strike through open lanes. Burn them to take them back, or re-develop them in the darkroom.

A story under the table

HALE remembers your choices between runs, copies your favourite cards and changes as it loses control. Your family's voices reach you from outside.

How to play

Five lanes, one table

  1. Place your memories

    Play cards into five frames on the table. Each memory has its own strength and effect.

  2. Read HALE, then surprise it

    Block its fakes and strike through open lanes. The less predictable you are, the more it bleeds.

  3. Choose what to keep

    After a win, keep a memory to grow stronger, or skip it to keep yourself whole.

Questions

Frequently asked

The screen flashes and shakes. Can I turn that off?

Yes. On the title screen, tap Comfort. It removes flashing, shaking and glitch effects, and turns on automatically if Reduce Motion is enabled.

Does the game know when I take a screenshot or leave the app?

The game's character reacts to those moments as part of the story. Nothing is recorded or sent anywhere.

Is my progress saved?

Yes, on your device, after every stop on the map. If you close the app in the middle of a match, that match restarts when you continue.

Is there more after Act I?

Acts II to V are in development. Each act has its own map, enemies and rules.

When can I play?

Loss Function is coming soon to iPhone and Android.
