Review Not Not 2 – A brain teaser: Brain trainer

A cube appears with short Dutch instructions. It’s up to you to sweep in the right direction. That sounds easier than it is in practice. Not Not 2 regularly uses double negatives, which quickly puts you on the wrong track. For example, consider commands such as “Not not down” and “Not not left.” Each level consists of thirty such commands. Furthermore, some levels have reversed controls. A mistake is therefore easily made. There is a short time limit of a few seconds for each step. In short, thinking for a long time or reading instructions several times is not possible.

One downside is the significant amount of advertising. For example, an advertisement is permanently visible at the bottom. In addition, a video commercial appears after each level. Do you find that disturbing? After paying a small amount you hide all advertising.
