I enjoyed it, but the levels felt very easy. I'd also suggest some way to work in words like mutex or semaphore more. If you named every variable xxxMutex for example the game would do a better job of teaching the vocabulary (I think). As is, it's easy to just manipulate the threads without really knowing the names of the synchronization elements.
