ABYSS: Echoes Never Leave

Every Sigil you play stays.

ABYSS is a turn-based deckbuilder built around one rule. A Sigil you play
does not go to the discard pile — it enters a queue of three slots, and
every card in that queue fires again at the end of every turn.

So playing a Sigil pushes one out. The engine you spent five turns building
can be undone by the card in your hand right now — every play is also a
choice about what you give up. The queue even fights on its own: there is
an achievement for winning a fight without playing a single card.

- Three heroes who each treat the queue differently: hold it still,
arrange it, or empty it as fast as possible
- Eighty-seven cards and forty-five relics, seventeen of which
rewrite the queue's rules outright
- Four acts, twenty depths of difficulty, and a final boss that turns
your own echoes against you
- Forty Game Center achievements. Signing in is optional — everything
works offline
- No ads, no purchases, no account, no network. You buy it once and it
is yours, offline, forever.

Runs take twenty to forty minutes. It is built for a phone, in portrait,
one thumb.

Accessibility: reduce flashes, disable screen shake, and three animation
speeds — all in Settings.
