It took >5 seconds to respond to my ls command, and then the first time I typed a challenge name nothing happened. I sat there waiting for something to happen, and then eventually typed it again (I tried to tab-complete and highlighted my address bar) and it asked for my authorization, even though I had just authorized two minutes earlier. That was when I quit. I would focus on making it more user-friendly before making new challenges.
