About this game

Working conditions:
Z-corp™ has successfully managed to build over 80 Trials™, offering a wide selection of style, difficulty, and methods of resolution. Thanks to our partnership with Dedra™, even more Trials are available to run, including the iconic with rugged good looks OvO.
Bask in the summer heat of the Desert Temple™ or cool down in the unique Winterland™ - possibilities are endless (1).
(1) - By endless Z-corp™ means that you are allowed to repeat the trials an indefinite amount of times.
Management Parallel: Build more Trials™
As a Builder™, you have the most important job at the company. With our built-in Level editor™, possibilities are endless - make your own handcrafted trials for all your subordinates to try and run.
Studies have shown that playing your own trials is considered good work. Be your own manager in this creative endeavor, enjoy the bigger responsabilities and take pride in the extra hours you'll put in.
Feeling stuck for ideas? You're not the first, and that means you can draw inspiration from the hundreds of existing trials made by other Builders™. Just know that your work was just a little worse than those you work with.
Join the Z-crew™ and build whole Trials™ packs for the whole world to enjoy.

Disclaimer and complaints:
If you are unsatisfied with the number of available Trials™, please write down a formal complaint and direct it to your manager. These complaints will be taken into consideration for the next shareholder meeting in August 2140.
If you are unsatisfied with the work you provide, so are we.
If you are unsatisfied about your unsatisfaction, please write yourself a formal complaint.
