Congratulations! And thanks for the comment too.
I tried to place it mostly on the center but I know there is a little less space on the sides than up and down. Did you feel that it was also not in the middle in vertical axis? Would you consider it better if the whole game was zoomed out a bit? I tried experimenting with this earlier but zooming out also makes everything look smaller on the screen which also makes dodging projectiles difficult. The problem is finding the right balance.
