The aim of the game is to enter the correct letter depending on the outputted letter. For example, if "a" was the output i would enter "a", but if "a>" I would enter the next character in the alphabet to the right ("b"), if it was "a<" i would enter "z" the next character to the left. Give it a try, your scores are recorded and the top 10 players will be displayed when you lose the game. Good luck
If you enjoyed the game Please Upvote, it is a very simple game, if there are enough upvotes i will consider making a tutorial for these kinds of games; similar to one I've made for Nims here: https://repl.it/talk/learn/How-To-Make-A-1-Player-Nims-Game-Nodejs/7610
Also have a look at my other game Making Friends, It's a lot of fun and could benefit from upvotes. Thank you.
