I think it's a nice game, it's just a little unfamiliar to me that the "?" blocks can only be hit on its' left side and the little shots we can shoot are on the S and F keys.
Yeah, I liked that they are different, people are just so used to it that maybe we just need a little indication like an arrow on the side to show that we are supposed to hit it there. For the controls, just maybe use the A and D instead. And no problem! I had a great time trying your game out!
