Leaves some room for improvement
As a video game fan, Tetris is something that you just never get tired of. The thing that did annoy me was how there didn't seem to be that much detail in this. There was not much of an attempt to have a lot of shading or anything like that. It's not terrible, and it actually is a bit of an original idea for a game even if it was modeled after Tetris. The music was alright. On the fourth or third level, I was just stuck with what to do.
Sometimes the pieces just had to fall where they may. I liked the little clip clop sounds the tiles made. You could work on some minor things too, like more elaborate music and a background with shadows and shading. I can see potential for this as the idea isn't half bad. While it looks pretty pleasant, it could have more detail.
