BETA 1 PRECISION MEETS CHAOS

ONE MOMENT.
ONE STOP!

One red button. One target time.
And one moment that makes the difference.

ONE BUTTON. PERFECT TIMING.Meet your opponent: time.

Sounds simple.
Until you press.

STOP! is a precision timing game by BlackJoker Studio. Stop the clock as close to the target as you can. Your timing decides whether the next door opens.

At first, there’s room for error. Then the windows get tighter, the rooms change, and the display doesn’t always play by your rules.

01

Know your target

Check the target time and the allowed tolerance. The countdown gets you ready.

02

Hit the moment

Space or left mouse. One press makes the difference between almost and perfect.

03

Open the next door

Pass the task, unlock the next room and take on a new challenge.

02 / THE CAMPAIGN

Ten rooms.
Less room for error.

Workshop, storage, darkroom and more.
Every room has its own character.

Room 1: training room with a red STOP! button and wall display.
ROOM 01 / 10First Steps

No installation or game account required.

Your stats and saves stay on your PC — even when you replace the EXE with a newer version.

04 / GOOD TO KNOW

Before you press.

What are the controls?

WASD to move, mouse to look around. Space or left mouse stops the clock. E collects nearby bonus coins. Escape pauses the game or goes back.

Does everyone have their own progress?

Yes. Coins, unlocked rooms and stats are saved locally. Different PCs or Windows users have separate saves. People sharing the same Windows user also share the save.

Is STOP! finished?

This is Beta 1. All ten rooms and three game modes are playable. We’re still working on polish and new ideas. A planned progression tree is not included yet.

How do updates work?

The update system is prepared. Until the online source is configured, replace the EXE manually with the new version. Your saved progress is kept.

How do I report a bug?

Tell us on Discord: your version, game mode, room number and the steps that caused the issue. A screenshot and your FPS help. Please don’t post personal save or log files publicly.
