The resource was tested by a student of B1.3 level (CEFR). It was appreciated: the game activities were different from those usually presented in a language course and they were motivating, especially the crossword puzzle.
Language proficiency improved because it was a fun way to learn new words and to study vocabulary. ("It always works to use games for studying"). The programme, however, provided too common words and their quantity was also scarce. Also, the programme only allows one correct answer, although there would be more. There are no explanations of the errors (for example, it gives error even for a wrong accent and does not communicate it). As for the adjectives, one does not know whether to give the masculine, feminine or both forms; as for the nouns, one does not know whether to include the article, etc.; further, it is unclear whether points can be earned with exercises and, if so, what they are for. The rules of use should be explained more clearly to learn more effectively.
The resource could be motivating, because it offers different ways of studying vocabulary (a task that can be boring otherwise). It is probably especially suitable for very young students who often have more technical knowledge and are more interested in (video)games.
While it's not a never-before-seen product, it's quite innovative: it uses different and fun approaches to learn the same lists of words. However, some critical points were highlighted on a technical level. Among the different links to use, there was a bit of confusion: one did not work, the same one (shared with Google Classroom) did. Once the page was closed, it was difficult to find it again. On the platform it was not easy to understand its structure and all the functions and to access the activities.
