Historical difficulty of CHR$(143) no longer stands in the way of a deeper discovery of the game
Opt for the easier difficulty level, with a smoother learning curve, and go further in the game!
Version 1.30 is designed to make the game more accessible with 2 major additions:

the player can opt anytime for the easier difficulty level (currently available for most of the first 22 levels, as well as for a few more advanced ones...)
graphic explanations are available in some briefings in order to explain complex mechanisms in greater details
Whether you're an old owner or a newcomer, access the full richness of the CHR$(143) universe!

Version 1.28 has been released :-)
This version introduces a fun new feature (which has been much requested...)
Four new building strategies have been introduced. These are explained at the end of level 11, but if you have solved it already and don't want to solve it again, here are a few hints:
the 2 historical strategies ("upward" and "downward") are now completed by "leftward" and "rightward": nothing revolutionary, the agent builds in an imposed direction (and digs in the opposite direction beforehand): simple and stupid, but very predictable...
the 5th strategy is "bestward": the agent chooses the best of the first 4 strategies according to what there is to build (which is often sufficient and relatively predictable)
the 6th and last strategy is "smartward": this is by far the most advanced one, but it is much less predictable (even if perfectly deterministic) and, let's be humble, rarely as perfect as what one could do with one's own brain! However, you might get used to it (and it's a bit hard to give it up...)
In any case, none of these strategies should damage your agent, unless there are danger zones nearby...
PS. you can use the setup menu to set the default strategy when entering a level...

New Workshop Level "Water, water"

This is an original workshop level with a very simple goal:
You have an infinite source of water and you need to pour as much as possible into the big pipe in one minute! That's all...
Design the device of your choice, whether it is automatic or manual, whether it uses CPUs or not... and maximize that amount. By checking the worldwide statistics sharing in the setup, you can compare your result with other players...

Can you dump more than 1000m3?
What is the maximum possible?
Who will be the World Champion?
Don't be shy, have a try ;^)

New Workshop Level "Automatic Raindrops"

Version 1.27(.03) introduces various developments, the most notable of which are:

Korean language support (thanks to the recent evolution of DeepL...)
level polishing, again and again, integrating various feedbacks and notably the latest known twitch stream (level 4 is less and less nightmarish btw!)
some bug fixes (one of which paralyzed the agent while trying to move a too heavy load...)
and, last but not least, an experimental global workshop-levels-statistics management feature: optimize your design and win the first place! (requires checking the "statistics sharing" option in the setup menu)
I'd like to take this opportunity to thank all the CHR$(143) players, all over the world, with a special mention to those who share their experience on the Discord or, even better, through reviews... (and sometimes both, for the most exceptional among them ;^)
Greetings to all!

Updates notes for 1.26.28: Chinese translations improved!
Since the machine translation into Chinese was not very good, UnluckyNinja has re-translated large parts of the original texts into simplified Chinese! Many thanks to this generous contributor for this great work: it should make the game more accessible to native Chinese readers.
