Played through the first levels and I really like the idea. I've been thinking about how I could get my kids started and this seems like a great way.<p>I also see possiblities for some really cool stuff for more experienced coders, especially in multiplayer.<p>Mentioned earlier: make it completely playable through keyboard. When I got the first alert that I had to use "enter" to continue I was thinking how great it was it was just keyboard and then it started mixing up.<p>I understand the server being hammered so errors pop up that shouldn't be there. But if I didn't have the knowledge level I have (simply being sure that the error was wrong and the code was right I might have bailed out in the first couple of lessons by not being sure what to do. So I think you should also put some thought in helping people new to coding navigate the errors also when they are not due to server error.<p>I will play it through as I'm curious how you'll make it more difficult, or better put, make it so that the player needs to program more instead of just putting the right commands in the right order. I can see it getting out of hand rather quickly on the development side :) But things like different classes that you can execute based on stuff happening on the screen would be great.<p>Good luck!
