piano tiles game
Overview¶
This mbed mini-project creates a game called “Piano Tiles”, where the user has to tap on the black tiles while avoiding the white tiles. Each correct tap results in a musical tone played, and in quick succession plays famous song Fur Elise. The score is measured on the speed of the player. For more info on this game check out: https://en.wikipedia.org/wiki/Piano_Tiles and you can also play an online demo here: https://scratch.mit.edu/projects/21596393/
