Thx for feedback! :)
Now you can use alternative controls. To start press key "S" instead of Num5 and then blocks will have Q,W,E,Z,X and C.

Really like it! I thought it was going to be a catch the falling objects game but I was pleasantly surprised. Had a bit of tetris and reflex game thrown into it. Overall I think it works pretty well together. I liked waiting for two blocks of the same letter right next to me to get rid of them in one go. I couldn't figure out what the "W" block was at first I kept hitting H until I realized that made no sense. Its pretty hard to fit a W on such a small block though. My highscore was 41. Good job!
