So sorry,  Actually I was trying to work on high score system  using player prefs  but  when I tested it on itch.io it shows error. I left this bugged updated version as it is, cause I thought no one was gonna play a generic game like this, I will surely update it today. 

Thanks for trying my game.

Fixed the issue, now you can play it :) , though I will surely implement the character switching and high score system in future.
