Recent Dark Pattern Reviews

Advertisements reported on May 30, 2022
An intrusive ad plays ever so often when the player is connected to the internet.
Infinite Treadmill reported on May 30, 2022
The game is never ending and repetitive.
Invested / Endowed Value reported on May 30, 2022
Some items can only be obtained by watching ads, and those items grant the player otherwise unattainable bonuses.
Can't Pause or Save reported on May 30, 2022
The player cannot pause or save the game mid level.
Aesthetic Manipulations reported on May 30, 2022
After each level or so, the player is given the "opportunity" to unlock a bonus modifier or an item by watching an ad. It is often accompanied with the options along the line of "Watch the ad" or "Lose It". "It" here being the item. This creates a feeling of urgency to get a special deal. But after playing a few levels, it becomes clear that the offer reappears every other level with a randomized reward.
