It works perfectly now! Guess third time was the charm. 
Nice little polished game (reminds me a little bit of the game blocks from kongregate) and the idea with the “big blocks” is really nice.
But imho it is too easy at the moment … I had to try only level 50 serveral times to get the gold medail.
It would be cool to see an editor with upload function. Then I could try to make harder levels. =)

Nope, the first one where no version number. And to make up my previous report: Mint 14 Java 1.7.0_21 64bit.
Updated with a harder level generator after about layer 5.

Still way too easy, but a nice game nonetheless. The only two problems I have is that my mouse down actions in the web version sometimes get a little bit delayed so the first block isn’t highlighted, and that it infinitely looped on me once when I was combining two block with a third color.

Which level(s) did you try that were too easy?
I think at a certain point that brains like programmers are going to find puzzles easy - but maybe the averagnaught won’t?

Pretty much all of them 
They eventually became more complex, but by then it was really easy to see which order to remove them as each level ends up similar.
Maybe you can skip the algorithm on the last 10 or so levels and create really tricky levels manually?
