Simple and effective
A highly engrossing game that I've never encountered anything similar to during my time surfing the internet. I think that the mechanics are well worked out, although I would question how the level system works - perhaps you could install something like you need to get so many blocks out into the Tetris field before a certain time of the day, since you're working in a factory. Perhaps put the score summary after each level has been cleared onto a clocking card, for example.
I think that it's a ncie little game with good potential to expand into bigger and better things, so I'll be looking forward to seeing how you take this forwards.
