The steam version supports 5 playable characters.
You do need to download the game.
thank you for reply.so there is no access to play characters on mobile?:(
I saw it can only download on PC or mac,and don't support to download on phone.if it can play on mobile then I can play it wherever I am.(i did load this website in advance then play it on plane to kill time)
nice game and hoping for more playable stuff on mobile!(><)
