It was nice but there didn't seem to be a need for points or a timer since there was no real penalty for the taking too long aside from bonus points. It could have used something like getting bonus screens for getting more points or needing x amount of points to get to the next screen. Something to think about if you make another.
A fun game! It is a bit limited though. I really hope you plan on making a sequel. I have to agree with some people here about the shooting aspect. I would prefer an automatic defense rather than manual shooting but you could consider it being optional or something you upgrade for people who do like it.
