This is the first musical game I ever made. The game has 2 templates one for desktop devices and another for mobile devices.
The desktop version uses the keyboard to play, all letters, and for mobile touch.
Feel free to comment or to try it at https://crazygames.cc/piano-simulator-online/play/ .
The game is available to embed to your website at gamemonetize.com.
The desktop version, has also the option to record, listen and to download it in any format you choose.
