If you could choose your starting level, this would be a really good game. As it is, the start is waaayyyyy too slow. Remove any motivation I have to replay this.
Also the typing detection needs some work. Often I type the right letter and get -1 blam instead of destroying the target (I know it's the right key because I keep pressing it and after a couple tries the target explodes). Happens more often right after destroying something, but not limited to that.
