Early Access Game

What the developers have to say:

Why Early Access?

“TOWERMOUTH is complete from the first floor to the Tower's mouth: twenty floors on the clock, a Warden every fifth floor, then HELL, which never ends. What it needs now is people climbing it. Our balance comes from our own playtests and test runs, and a co-op roguelite only gets truly balanced when real solo players and real pairs show us where the Tower is too soft, too cruel or too samey. Early Access lets us tune it with you while we keep adding oaths, Wardens and secrets.”

Approximately how long will this game be in Early Access?

“About 6 to 12 months. We will leave Early Access when the additions below are in and the balance has settled with real players, not on a fixed date. We will announce the 1.0 date on Steam ahead of time.”

How is the full version planned to differ from the Early Access version?

“The core stays the same: a twenty-floor climb on the clock, solo or two-player split-screen, where your weapons fire themselves and the Tower talks back. What we plan to add during Early Access (plans, not promises):

- More oaths, each one changing a rule of the game.
- More Wardens and rooms for the four zones, and more of HELL.
- More dares, legendary relics and secrets in the walls.
- Balance passes based on what Early Access players run into, solo and co-op.”

What is the current state of the Early Access version?

“Fully playable, solo or in two-player split-screen co-op on one PC:

- A full climb: 20 floors on the clock through four zones (COLD, UNCANNY, SICK, NIGHTMARE), a Warden every fifth floor and a final Warden on floor 20. Win, and HELL opens below; HELL never ends.
- Five DEPTHS: beat the Tower to open the next one, with sturdier creatures and an enraged final Warden.
- 20 weapons that evolve, and every one of them can awaken into a new form.
- 10 legendary relics, 11 ultimates and a deck of items, curses and rule-benders.
- 11 oaths: swear one before you climb - a starting weapon, one rule and a cape. In co-op each player swears their own, or you both swear BLOOD BROTHERS and share every wound.
- 51 dares that unlock new weapons, oaths and cards, plus a new DAILY DARE every day for TODAY'S TOWER.
- Steam leaderboards: solo, co-op, friends and a daily board.
- 4 difficulties and 4 modes (STANDARD, ONE CLUB, DAILY TOWER, DUEL couch PvP). 3 lives per climb, and the climb saves at every gate.
- Two gamepads, a gamepad plus the keyboard, or one shared keyboard. 15 languages (text only). 37 Steam achievements and Steam Cloud.

Known rough edges, in plain words:
- Windows only. Steam Deck has not been verified yet.
- With Steam Input on, PlayStation pads show Xbox button names.”

Will the game be priced differently during and after Early Access?

“The price will not go down when we leave Early Access. As the tower gets deeper we may raise the price for 1.0; if we do, we will announce it well in advance. Everyone who owns the game gets every update at no extra cost.”

How are you planning on involving the Community in your development process?

“We tune TOWERMOUTH by what players actually run into.

- Steam discussions are where we read bug reports and balance complaints, solo and co-op.
- Every update comes with a Steam announcement: a line from the Tower, then a plain list of what changed.
- The game has no telemetry, so what you write in reviews and discussions is how we learn where the tower is unfair, too easy or confusing.
- Co-op feedback matters most to us. If you and your partner find a moment where one of you has nothing to do, tell us.”

About This Game


"Experiment 4051 begins. I wiped the previous 4050 into the stairwell." - the Tower

ONE TOWER. TWO KNIGHTS. NO PATIENCE.

Two of you, one screen, one very rude tower. Every floor runs on a clock: hold out while the Tower grows impatient and the horde grows hungrier, then take the stairs. Twenty floors to the Tower's mouth. Win, and HELL opens below - and HELL keeps going. Solo works too - the Tower just has more time for you.

YOUR WEAPONS FIRE THEMSELVES

You never click to attack. You move, you dash, you drag your partner out of the fire. 20 weapons, from a CLUB to an actual FISH - and picking the same one again evolves it. Swear an OATH before you climb: the Butcher's axe, the Archer's bow, the Shadow's dagger. One weapon, one rule, and a cape to match - or, in co-op, swear BLOOD BROTHERS together and share every wound. Carry the right catalyst and every one of them awakens into something new.

BUILDS THAT GET STUPID

Stack five copies of an EFFECT card and it stops being an item: STORM RING becomes LIGHTNING ROD, BLAST FIST becomes FUSE FIST. Keep stacking it - EFFECT cards have no cap. Stand close to your partner and your builds fuse.
"That is not a build anymore. That is weather." - the Tower

EVERY ZONE IS A PLACE

A cold rotunda with an arcade and a medallion. A long UNCANNY nave of arches and lit niches. A SICK ward crowned around a bottomless well. A NIGHTMARE cross built around a rose medallion. And HELL - the burned twin of the first hall, with the Tower's core beating at its heart. Most floors have their ruin - a crashed chandelier, a toppled monument, a memorial built from the weapons of climbers before you - and on the SICK and NIGHTMARE floors, the Tower has already started to digest it.

On many floors, low stone screens shape the fight: hop over them while the horde has to go around, and let the stone eat the shots aimed at you. A Warden guards every fifth floor, drawn from its zone's pool of five, so the four you meet change from climb to climb - and THE COLLECTOR shows up carrying copies of your own weapons.

ONE MORE CLIMB

Beat the Tower to open the next of five DEPTHS. 51 dares unlock new weapons, oaths and cards; Wardens hand out ten legendary relics; and the walls hide more than stone. Your deepest climb goes on the Steam leaderboards - solo, co-op, friends and TODAY'S TOWER.

"They're one floor up. They're always one floor up. I make sure of it." - the Tower
