I think that this is great and I just want to make a suggestion. I see a lot of these &quot;learn to code&#x2F;css&quot; run into the same problem where they don&#x27;t feel like real games. Give the player a dilemma such as dying if they don&#x27;t type the right command fast enough. Resetting the level if they fail.<p>edit: lvl 15 makes colorblind kids sad :(<p>edit2: almost, almost <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;egndPZ8.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;egndPZ8.png</a><p>edit3: champion!
