Great base to build off of
Love the concept. Nice and simple and easily addicting. I think this has lots of potential to evolve into a great game. I am glad that you've decided to work on more levels rather than a level editor. Different blocks are a must. I also would recommend perhaps power-ups that are attainable. Hopefully you are able to finish soon, I look forward to playing the new version, especially if there is a progress saving mechanism. Maybe medals? I also would enjoy the ideaof having different sized blocks having a blatant score, perhaps outlined in the tutorial.
