Alnis, love the game! But I also ran into unexpected behavior after clearing level 7 (change your color). It kept reloading the same level, but opening up new levels in Level select. Even so, clicking on higher levels keeps reloading the same colors.js screen.

Another weird thing I noticed was that next to the computer and telephone in the inventory, two letters "k" appeared. I'm using Firefox 28 on Windows 7.

Here's the solution I used for colors.js https://gist.github.com/anonymous/ab5cd3b393c290fbf8c1

Bizarre! I haven't been able to reproduce it. Can you share your code for that level (if it's been modified at all)?
