It was a simple nice game, I really liked the simple style and sound effects. However the controls kinda got on my nerves. I don't know why. I just make mistakes in pressing keys, I use arrows to rotate, a and d to resize, maybe pressing buttons fast isn't my talent lol. I feel that first two levels were too easy, and last two levels were too hard, maybe if there was an average level I could better learn the controls. I tried a lot to pass the boss level, I haven't yet, I just miss one block and other blocks also go as fast as a SMG shooting bullets. I feel more speed would be a better difficulty modifier than gap between blocks.
Edit: I finally passed the boss level, it was easier for me when I adjusted the rotation and position first and then resized the block. The difficulty curve was really hurting enjoyment. And one wrong thing I was trying with I've known was trying to hold buttons, maybe a delayed movement would be good because pressing left and right accurately is hard in low time. (Or at least it was for me)
