Sudoku Zenkai - Online Update - 1.1.0 Changelog
Hi guys!

We've been working on the latest update of Sudoku Zenkai, adding one of the most requested features, true online co-op.

From today on you will able to create public rooms where anyone can join! Making all those co-op achievements easier to achieve and generally giving all users a chance to play co-op puzzles with other players.

We also added a few tweaks requested by the speedrun community (yep that is a thing :D). Now the game displays a simple * in front of the difficulty if the player used any helps or paused the game mid session. We also extended the time to include milliseconds.

Finally a big shoutout to Jiří Řáha for helping us bring the game to all Czech native speakers!

The rest was the usual bug fixes and optimizations, hope that you guys enjoy it!
