The writing is hard to read, hitboxes are too small and the timer is just awful. ### 3/5 — Bien mais trop dure *2021-11-21, version 2.7* Appli intéressante mais certains niveaux sont trop compliqué à atteindre ### 3/5 — Chapter 2.2 doesn’t work *2021-02-14, version 2.7* The music won’t play in chapter two. ### 5/5 — Très bonne application *2020-11-10, version 2.7* L’application a peut être un niveau légèrement compliqué mais elle met un œuvre des faits scientifiques importants et je trouve ça nécessaire. Très bonne trouvaille ### 5/5 — 6.3 *2019-08-31, version 1.5* Chapter 6.3 doesnt work ### 5/5 — Me encanta *2019-07-12, version 1.5* La mejor aplicación de mi vida ### 1/5 — Decepcionante. Necesita muchas mejoras *2019-06-21, version 1.5* El juego puede resultar muy frustrante si no consigues superar un nivel, te quedas atascado en el juego y ya no puedes seguir. El problema es que el juego tiene fallos y las pruebas no dan ningún margen de error lo que hace imposible superar algún nivel y por tanto seguir con el juego. La continua publicidad salta a cada momento interrumpiendo el juego y teniendo que volver a empezar, por lo que entras en bucle y no hay forma de acabar un nivel. He pagado para quitar los anuncios y después de gastarme el dinero siguen saliendo a cada momento, por lo que me siento estafada. NO RECOMIENDO EL JUEGO Y SI ALGUIEN QUIERE DESCARGARLO, NO TIREN EL DINERO PARA QUITAR LOS ANUNCIOS PORQUE NO LOS QUITAN. ES UN ENGAÑO ### 2/5 — Falló en los cubos *2019-05-07, version 1.2* El juego está genial, pero tiene un fallo en la prueba de los cubos, no resta el agua que hay en el cubo de 4l. Así es imposible pasarla. ### 5/5 — Muy interesante *2019-04-11, version 1.0* Juego muy interesante, con una dificultad alta, y que nos enseña a la vez que nos divertimos. Muy recomendable. ## Frequently asked questions about Einstein's secret book ### What is Einstein's secret book about?
