I joined a small coding competition on Khan Academy for fun and to practice some frontend coding skills and here's what I got as an entry.
I'd like you to test if out and see if there are any bugs in there, offer some feedback on it, etc.
One of the challenges I had to deal with was the fact that there were no Live Websites on Khan and that there was a bunch of limitations. I was able to get past those and made a very nice text adventure.
The goal of the game is to kill as many enemies as you can and invade the aliens' base in the game to win.
I hope you enjoy my creation!
Have fun and Happy Coding!
