Black Zen White

2-player co-op and french translation in demo update 1.5.1!

24m² Studio

Hello everyone!

Black Zen White demo has been updated to version 1.5.1 and includes, among other things, a 2-player co-op mode and french translation (which you should not care about since you are reading this in English)

The demo is preparing for the upcoming Steam Next Fest starting on February the 23rd! If you want to support us, you can play the demo (again) during the festival (ideally on the first day) and spread the word around you.

What's new

  • 2-player co-op mode
  • Can add/remove a player anytime from the menu
  • No controller? No problem! 2 players can play on the same keyboard
  • Several shared keyboard setups available
  • You can play locally on the same computer and online with Steam Remote Play Together !

French translation

Add a title screen at the beginning of each level adding to the calm atmosphere and making sure players won't miss potential clues

Automatically enable HDR for compatible monitors

Changes in keyboard setup

  • Jump with [W] and [up arrow] in addition to [space bar]
  • Zoom with [H] and [E] (instead of [N])
  • Fast forward with [K] (instead of [J])
  • Pause/menu with [F1] (instead of [P]) in addition to [Esc] ([P] is used in some 2-player shared keyboard setup)
  • Yes it can seem a weird choice of keys but it's needed for the full game...

Input device (keyboard / controller)

  • Detection/selection of the input device at game start
  • Until now, the game was switching from one device to another depending on which was in use. This was causing problems if you had a connected controller with stick drift.

1-player mode

  • automatically select new connected controller during game
  • if selected device is disconnected, pressing jump button on another device selects it

2-player mode : if one of the players devices is disconnected, game is paused and shows the input device selection screen

Better vibrations management

Button to submit is now always controller "south button" even with a Switch controller

Music now continues even if game is paused

Settings menu

  • Add input device selection
  • Add language selection
  • Add monitor selection
  • Remove FPS counter (We needed some space. You can still enable it with Ctrl + F10 and Ctrl + F11 )

A lot of bug fixes

Most likely some new bugs

Thanks to everybody who played the demo and gave us some feedback. It helps us a lot to make the game better!
