About the game

"Save the words" aka "Falling words" is a small language learning game for Android. As soon as the game starts, an English word will be shown at the bottom of the screen. A word from another language (For ex: Spanish) falls down from the top. The player should tap the green correct button if the falling word is a correct translation of the English word or the red wrong button if the falling word is an incorrect translation of the English word.

The fun part is that the speed of the falling words will increase dynamically through the game as the player scores more points. In a gaming session, the player will be given a maximum of 3 lives. The game ends when all the lives are exhausted or when all the words are exhausted.

Note

The UI of the app is not polished. I'm still working on it.
