Thank you Richard for your very kind words. I always wanted to make something in isometric style and this came out of it. Tetris is a wonderful game concept because you don't need to design any levels - just a random number generator. The basic mechanics speak for themselves. But I am quite happy how my design implementation worked out. For example, it was important to me that you can turn or push a block into position in the very last moment. And being able to turn the whole tower is helping a lot to deal with the (sometimes a bit difficult) isometric perspective. All in all, this was a nice little project. Happy that you like it.
